Bugstronaut Launch Instructions

Pop – Fizz – Fly! Get Ready for Launch

Peel off the sticky backing from your Bugstronaut’s feet and stick them firmly onto the outside of the rocket lid.
Make sure your Bugstronaut is safely attached and ready for the ride!

Add the Water

Pour one tablespoon (15 ml) of water into your rocket tube.
This is your starting volume — you can experiment later to see how the amount of water affects your launch time and flight height.

Pop in the Tablet

Drop in one vitamin C tablet — this is your rocket’s fuel!
This is a starting amount — you can experiment later to see how changing the amount of tablet affects the height and time to lift-off.

Fizz!

The tablet fizzes in the water, producing carbon dioxide gas (CO₂).
As the gas builds up, it increases pressure inside the closed tube.

Fly!

Quickly push the lid on tightly, keeping it pointed away from your face.
Place your rocket upright and step back (or hold it out at arm’s length).

Now wait for lift-off!
You won’t see the pressure building — but it’s happening inside the tube!

The time it takes for your Bugstronaut to blast off depends on:
1⃣ How much carbon dioxide gas (CO₂) is being produced, and
2⃣ How firmly you pushed the lid on.

When the pressure becomes too great… POP!
The lid flies off at speed, and your Bugstronaut blasts into the sky!

Did You Know?

Gas pushes outwards in all directions inside your rocket tube.

As the fizzing tablet reacts with the water, it produces carbon dioxide gas. The tube already contains air, so the carbon dioxide molecules mix with the air molecules inside the tube.

Because there are now more gas molecules moving around in the same fixed space, they collide with the sides and lid more often. These collisions increase the pressure inside the tube.

When the force pushing upward on the lid becomes greater than the friction holding it down, the lid pops off and launches your Bugstronaut!

Bug Blast Launch Lab

Can you get the bug home?

Mission Briefing

Your bugstronaut is about to embark on a daring space mission — but first, we need to fuel the rocket! Add water and a fizz tablet to your rocket tube, snap the bug-topped lid into place… and wait.

Nothing seems to be happening at first, but inside the sealed tube, something incredible is going on. The tablet is fizzing away, releasing an invisible gas called carbon dioxide. As the gas builds up, the pressure rises higher… and higher… and HIGHER…

Suddenly — POP! WHOOSH! Your bug blasts skyward, ready to return home to its planet! Can you aim carefully enough to land your bug safely in its home planet bucket?

What’s Happening Inside the Tube?

The fizzing tablet contains citric acid and sodium bicarbonate (sodium hydrogen carbonate). When they mix with water, they react to make carbon dioxide gas. The gas has nowhere to escape, so it builds up inside the sealed rocket tube. When the pressure becomes too much, it forces the lid off — and your bugstronaut launches into orbit!

This thrilling moment is a perfect way to explore:

• Chemical reactions (acids + bases → gas)
• Gas pressure (invisible forces at work)
• Rocket science (Newton’s Third Law: for every action, there’s an equal and opposite reaction)

Bug Blast Launch Lab — Mission Safety Checklist

Protect Your Eyes

• Wear safety glasses if you have them.
• No glasses? Swimming goggles, sunglasses, or other protective eyewear are perfect alternatives.
• If you already wear glasses, keep them on — they’ll help shield your eyes.

Keep Hands Dry

• Dry hands only!
• Wet fingers can make the tablet start fizzing before you’re ready.

Safe Launch Zone

• Choose a big open space — a school hall, playground, or outdoors is best.
• Mark a safety line and make sure everyone stands behind it.
• Always point your rocket away from people, pets, walls, and windows.

Rocket Holding & Aiming Rules

• Hold your rocket firmly and vertically for the first launch — this gives the most dramatic lift-off!
• For subsequent launches, you can experiment with different angles:
  

  Which angles gives maximum range?

  • Around 45° usually gives the longest range.

• Never hold the rocket horizontally! As soon as the lid flies off, the water and tablet will shoot out too, creating a mess and a safety risk.

Special Advice for Indoor Launches

• Always test first: An adult should try one launch to check how high the lid flies.
• If the ceiling is too low for a vertical launch, all launches must be done at an angle — provided the room is long enough for safe distances.
• Make sure rockets are aimed away from people, furniture, lights, and windows.

The Waiting Game

• After adding water and snapping on the lid, hold steady — the fizzing reaction has started!
• You won’t see the gas building up, but that’s part of the suspense…
• Then suddenly: POP! WHOOSH! Your bugstronaut blasts away!

After the Launch

• Collect all lids and bugs after each blast-off — no bugstronauts left behind!
• Wipe up any spills to keep the launch zone safe and dry.
• At the end, wash your hands.

Bugstronaut Craft Zone

Before your mission begins, it’s time to design your rocket!

Decorate your tube to turn it into your very own Bugstronaut Space Shuttle:

Option 1 – Sticker Design
Use stickers to decorate directly on the tube — add stars, planets, or your Bugstronaut’s name!

Option 2 – Paper Wrap Design

1. Draw your rocket design on a piece of paper.
2. Add patterns, colours, and space symbols.
3. Wrap it around your tube and glue or tape it in place.

Science Tip:
Real rockets are decorated too! Engineers and astronauts add symbols, flags, and mission patches to show teamwork and identity.

Challenge:
Can you give your Bugstronaut rocket a mission name and logo?
Write it below or on your paper design!

Sparks of imagination are at the heart of creativity!

This Stirrup Pump with gauge is perfect for schools and teams to inflate numerous ball efficiently – but is also a great aid in the classroom.

Scientific Sue uses this pump for her Cloud in a Bottle Demonstration and her water rocket demonstrations.

Features an air pressure tank. spring clip valve lock, reinforced air hose and a fold down footplate.

• Quick and easy to use
• Standard size needle ( included)

In the Cloud in a Bottle demonstration, the students directly observe a cloud from right before their eyes – and when the bottle is connected back to the pump and the air pressure is increased they will see the cloud disappear!

Cloud formation is part of the water cycle, but one we usually cannot see up close.

A cloud is a large collection of very tiny water droplets or ice crystals. The droplets are so small and light that they can float in the air. When warm air rises carrying with it evaporated water, it expands and cools. Cool air cannot hold as much water vapour as warm air, so some of the vapour condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

This demonstration shows how water in the atmosphere can be made visible by changes in pressure and temperature.

Objectives

• Describe and illustrate the water cycle and associate parts of the cycle with weather conditions.
• Observe and describe changes to the properties of water when it is heated or cooled and associate these changes with weather conditions.

Materials

• Clean 2 L plastic bottle
• Cork with inflating needle 
• Stirrup or bicycle pump
• rubbing alcohol
• Safety Goggles

The post Stirrup Pump with Gauge appeared first on Science2Life.

When the bottle is pressurised by pumping air into it, the air molecules collide with each other and warm the bottle and its contents. Releasing the pressure causes the water vapour to condense quickly, forming a cloud.

What’s in the kit?

• Cork stopper with inflation needle
• 70% Rubbing Alcohol

What you need:

• 1-2 L, PET bottle
• Stirrup pump
• Safety Glasses

Secrets for Success

• Using the atomiser bottle pump 5 squirts of rubbing alcohol into your PET bottle (label removed).
• Push in the cork stopper – the further it is pushed in the more air will be needed to be pumped in to build up a high enough pressure to push it out.
• Attach the pump to the inflation needle.
• Hold the bottle with the cork facing away from you. Make sure you have a clear space of at least 1 m in front of you – the cork will leave the bottle at a very high speed.
• Get your volunteer to stand beside you with one foot on the stirrup pump base. They then have to pull the handle to its maximum height and then push down as fast as they can until the bottle and cork separate.
• You will end up with a fantastic cloud in the bottle.

Science in a Nutshell

In this experiment we are mimicking the part of the Earth’s water cycle in which evaporated water (water vapour) cools and condenses, forming cloud as they connect with dust. In this demonstration the alcohol acts as the dust, providing something cool for water droplets to attach to.

When the bottle is pressurised by pumping air into it, the air molecules collide with each other and warm the bottle and its contents. Releasing the pressure causes the water vapour to condense quickly, forming a cloud.

Bonus: Reverse the experiment!

Before the cloud disappears, put the cork back in and pump a couple more times. The cloud will disappear as quickly as it came. Release the pressure, and the cloud will form again.

How do real clouds form?

Clouds require three things to form:

• Water molecules
• Cloud condensation nuclei – dust or air pollution
• Temperature or pressure changes

Water molecules are in the air all around us, even though we can’t normally see them. Normally, these water molecules bounce around.

Real clouds form when warm air rises in the atmosphere and cools down. Cloud condensation nuclei, such as small particles of dust and pollution, enable water molecules to stick together and stop bouncing around. The water molecules condense around the nuclei to form clouds. Clouds are just groups of tiny water droplets that stick together around cloud condensation nuclei when temperatures are low.

High- and low-pressure systems cause day-to-day changes in our weather.

Ascending and descending air

Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.

In general, low pressure leads to unsettled weather conditions and high pressure leads to settled weather conditions.

Anticyclone (high pressure)

In an anticyclone (high pressure) the winds tend to be light and blow in a clockwise direction (in the northern hemisphere). Also, the air is descending, which reduces the formation of cloud and leads to light winds and settled weather conditions.

Depression (low pressure)

In a depression (low pressure), air is rising and blows in an anticlockwise direction around the low (in the northern hemisphere). As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. This is why the weather in a depression is often unsettled, there are usually weather fronts associated with depressions.

What’s in the kit

Balloon Pulley System

• 4 doughnut balloons
• 6 long double-sided stickers
• 10 modelling balloons
• 4 small (5″) balloons
• 10 Water balloons
• 10 Small double-side stickers
• Small water pistol

What you need:

Example of show tray for the virtual experience

• Balloon pump
• Air zooka**
• Safety glasses
• Permanent pen
• 2 x trays for the water balloon parcels
• 6 paper/plastic cups

Secrets for Success

• Blow up the 4 doughnut balloons – These will make the two pulleys. The two balloons of the same colour are joined together by the double-sided stickers (3 stickers per set. Have spare sticky dots, stickers to hand).
• Blow up the four 5” balloons to a size that the children will be able to hold comfortably.
• Tie two of the model balloons to two of the 5” balloons. Thread the model balloons down the middle of the pair of doughnut balloons. If the model balloon isn’t long enough, add another – this one has to be removed before you tie the other 5” balloons to the model balloons to complete the 2 pulley units.
• When the small balloons are pulled apart the doughnut ‘pulley’ should spin on the stretched (uninflated) model balloon, when you give a downward tap.
• Depending on the size of your room, inflate 6 or 8 modelling balloons and join them together to form a loop – this will be the rope that goes over the 2 ‘pulleys’.
• Inflate 6 of the water balloons.
• You may want to write on each of them: food, water, medicine, etc.
• Put one small sticky tab on the bottom of the balloons – make sure the protective cover is removed on both ends of the tab – otherwise the balloons won’t stick to the balloon rope.
• To prevent them from sticking together and blowing away put them into the 6 paper cups – if the workshop option was purchased used the cups provided.

You will be guided on how to construct the pulley system by me in the video.

Fill your water pistol – if the one in the box isn’t big enough by all means add your own!

In the video I suggest that you the teacher use the water pistol, you will be the rain in the storm.

If you have an airzooka I will also guide you to choose a 5^th volunteer who will be the wind in the storm. Have them stand between 1-2 m away from the other volunteers. Guidance must be given not to release air into anyone’s eyes – safety googles are recommended.

Science in a Nutshell

A pulley is simply a collection of one or more wheels over which you loop a rope to make it easier to lift and/or move things.

ONE PULLEY SYSTEM

Pulleys are examples of what scientists call simple machine. That doesn’t mean they’re packed with engines and gears; it just means they help to make work easier for us and can even help us multiply forces. If you want to lift a really heavy weight, there is only so much force ore muscles can supply, even if you are extremely strong. However, by using a simple machine such as a pulley you can change the direction of the pulling force (and use gravity to help with the lift) and with increasing numbers of pulley wheels can effectively multiply the force your produces.

The more wheels you have, and the more times your loop the rope around them, the more you can lift.

One Wheel

If you have a single wheel and a rope, a pulley helps you reverse the direction of your lifting force.

So, as in the picture below, you pull the rope down to lift the weight up. If you want to lift something that weighs 100kg, you have to pull down with a force equivalent to 100kg, which is 1000N (newtons). If you want to raise the weight 1m into the air, you have to pull the loose end of the rope a total distance of 1m at the other end.

Two Wheels

Now if you add more wheels, and loop the rope around them, you can reduce the effort you need to lift the weight. Suppose you have two wheels and a rope looped around them, as

TWO WHEEL PULLEY SYSTEM

in the figure below. The 100kg mass (1000 newton weight) is now effectively supported by two sections of the same rope (the two strands on the left) instead of just one (ignoring the loose end of the rope you’re pulling with), and this means you can lift it by pulling with a force of just 500 newtons—half as much! That’s why we say a pulley with two wheels, and the rope wrapped around it this way, gives a mechanical advantage (ME) of two.

Mechanical advantage is a measurement of how much a simple-machine multiples a force. The bigger the mechanical advantage, the less force you need, but the greater the distance you have to use that force. The weight rises 1m, but now we have to pull the loose end of the rope twice as far (2m). How come? To make the weight rise 1m, you have to make the two sections of rope supporting it rise by 1m each. To do that, you have to pull the loose end of the rope 2m. Notice that we can also figure out the mechanical advantage by dividing the distance we have to pull the rope by the distance the weight moves.

A block and tackle is a cable system primarily found on cranes and boats that involves two pulleys and a cable or rope. The mechanism consists of one fixed pulley and one movable, usually hanging, pulley. A single rope is fixed to on or near the carriage of the fixed pulley, loops down and around the movable pulley, then back up and around the fixed pulley. A hook is attached to the underside of the movable pulley, and by tugging on the rope, the hook will lift or lower.

• Suitable for indoor and outdoor fun
• The Air Zooka operates by pulling and releasing the built-in elastic launcher
• The column of air can travel over 4 m!
• Use it to knock down paper cups
• Or remove Grandad’s toupee

The Air Zooka is a wind tunnel in miniature, trapping air in its conical rear quadrant and firing it forward with elastic speed for maximum disruption.

Ruffle someone’s hair or cloths, push papers off tables, spook someone as the turn the corner – the possibilities are endless.

Paired with a smoke machine, this air cannon will fire beautiful smoke rings!

The proper name for this concept is the vortex generator, because the rings that are being shot out of the Air Zooka are actually flat vortices of air.

How the air moves when leaving the Air Zooka

The circle shape is created because the air in the centre of the air zoom is exiting faster than the air around the rim of the air zooka – hence this toy can be used to illuminate Bernoulli’s principle which states: The faster the flow of air becomes, the lower the pressure air becomes.

Safety: Never fire the Air Zooka in anyone’s face (people or animals)

A Science2Life Creation

From chaos to calm – make your own mini ‘snow’storm then we wowed by static magic!

A fantastic demonstration which can be used to visualise the fact that like charges push against each other and opposite charges pull together.

It is also a fun and creativity demonstration that can be used to help explain how lightning is formed in clouds!

TRANSPARENT LATEX BALLOONS 10 PACK with a small bag of polystyrene beads

The charged balloon is rubbed on hair, causing the polystyrene beads inside to stick to the rubbed areas due to static electricity.

• Size: 30 cm (12 inches)
• 10 pack
• Transparent balloons
• Made from natural rubber latex
• Bag of polystyrene beads

STATIC ELECTRICITY DEMONSTRATION

Secrets for Success

• A balloon pump must be used to inflate the balloons as there is too much moisture in our breath. Water prevents the build-up of static charge.
• Don’t over inflate the balloon – you don’t want it to explode.
• Store your latex balloons away from sunlight, preferably in an opaque container. Sunlight and ozone combine to oxidise the surface of the balloon which then weakens the balloon.

Science in a Nutshell

When insulating materials – in this case the latex balloon and the polystyrene beads – rub against each other, they may become electrically charged. Electrons, which are negatively charged, are pulled from one material on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with an overall positive charge.

The rubber balloon loses its electrons to the polystyrene beads.

Scientific Sue holds a charged balloon to demonstrate static electric forces during an Intel science event for students.

Like charges repel each other – this is why the polystyrene beads spread out on the inside surface of the balloon.

Opposite charges attract – this is why the polystyrene beads stick to the surface of the balloon.

When the balloon is rubbed on hair, charges move from the hair to the balloon. The balloon and the hair then have opposite charges. When you slowly lift the balloon away from the hair the electric force of attraction is strong enough to lift the hair.

The size of this force decreases with distance so as you keep moving the balloon away from the hair the hair will eventually drop. However, when you then bring the balloon closer to the head the hair will then spring back up!

Science in a Nutshell

Magic Snow is an erupting polymer! Magic Snow is actually derived from the superabsorbent polymer, sodium polyacrylate, found in baby nappies. The only difference (and it’s a big one) is that the Magic Snow polymer not only absorbs water but the long chains of molecules swell to an enormous size.

The polymer soaks up water using the process of osmosis (water molecules pass through a barrier from one side to the other). When water comes in contact with the polymer, it moves from outside the polymer to the inside and causes it to swell. The polymer chains have an elastic quality however, they can only stretch only so far and hold just so much water.

The Magic Snow reaction is a great example of a physical reaction – a reaction where the substance itself does not change. When an ice cube melts, a physical reaction takes place where the solid ice turns into a liquid, but the substance (water) never changes – it’s still water! However, in a chemical reaction, a new substance is formed and energy is either given off or absorbed.

If you think of the Magic Snow powder as millions of tiny sponges, it’s easy to see that neither the Magic Snow powder or the water was changed. If you allow the water to evaporate, the Magic Snow powder dries out and returns to its previous state, ready to be used again.

Also, because of water’s unique shape, it is capable of associating with two polymer chains. For this reason, two polymer chains surround each layer of water molecules, with each row of water molecules forming a bridge between the two chains. Imagine the polymer–water
complex as something of a molecular sandwich, where the polymer chains are the “bread” and the water molecules are the “jam.” This ability of water to link between chains is called cross-linking, and it is what allows the polymer to absorb so much water.

What happens when you put some table salt on top of the snow?

Salt causes water to leak out of the sodium polyacrylate because it disrupts the attraction between water and the polymer chain. When salt is added, it breaks up into negative and positive ions, which are also attracted to the water molecules. In fact, each ion attracts several water molecules to it. Eventually, when enough salt is added, the water molecules become more attracted to the ions than the polymer chains, and water leaks out of the mixture.
