Stretch Test with the Tri-String Wand
Before you start, make sure your tri-string wand is fully soaked in bubble solution. Play with the wand to create bubbles of all sizes and get the string ready!
To measure bubble length, use a measuring tape or mark the ground using foot lengths or strides.
Test Instructions:
- Dip the string section of the wand into the bucket of bubble solution. You have to make sure the whole of the string is covered. DO NOT STIR this will tangle up the string.
- Keeping the sticks of the wand together remove the string from the bubble solution. Lift the sticks high. Open up the sticks. You will see a bubble film stretch between the strings.
- If it isn’t windy you will have to walk backwards (safely!) to catch the air in the bubble film.
To make a bubble:
On a calm day: Walk backwards to let the air fill the film – you will need to practice the speed at which you walk. Too slow and nothing will happen – Too fast the bubble film will burst
On a breezy day: Stand with your back to the wind.
The wind will inflate the bubble for you! You don’t need to move – just open the wand and let the wind do the magic. If it is too windy the pushing forces of the air molecules will burst the delicate bubble film.
- Measure the length of your longest bubble at the point that it just pops or breaks.
- Repeat 3 times for each solution.
- Because wind can affect your results, should you repeat the test more than 3 times?

🧠 Science Note:
The large loop and gentle movement help trap air in the bubble film. The soaked string creates a stable surface that stretches into a giant bubble before breaking away.
💡 Top Tip: Close the Wands to Make the Bubble Fly!
When you’re ready to release your bubble, gently bring the two wands back together. This pinches the soap film and seals off the bubble, allowing it to float away instead of collapsing.
🧪 Why This Works:
- The soap film is like a stretchy curtain between the 3 lengths of string.
- If you don’t close the wands, the film stays openand the bubble won’t break off — it just pops or collapses.
- Closing the wands snaps the film shut, turning the long soap tunnel into a complete bubble.
Think of it like tying the end of a balloon — the air stays inside the bubble because you’ve sealed it off just in time.
