In this video Scientific Sue will show you how you can use Ooze Baff crystals in a very magical spell. A similar spell used by the Death Eaters in the Mr Potters Magical World. The death eaters suck up the souls of their victims – our ‘Death Eater Crystals (Ooze Baff crystals) suck up liquids! Use a little bit of science to find out how much the crystals suck up and still stay in a sticky solid format – then use that science in the Evanesco Spell. This video will take you through the steps you need to take to wow and confuse your audience – Science Magic – Fun Guaranteed!
The Science
Ooze baff crystals are an example of water absorbing polymers.
A polymer is a molecule, made from joining together many small molecules called monomers. The word “polymer” can be broken down into “poly” (meaning “many” in Greek) and “mer” (meaning “unit”).
Sodium polyacrylate are the water absorbing polymers found in babies nappies – the crystals Scientific Sue uses in her first EVANESCO Spell in the video below.
Water absorbing polymers soak up water through a process called osmosis and they swell up. Some, like Ooze Baff, just absorb a small amount of water. Others, like the crystals in nappies absorb huge amounts of water.
The polymer chains have an elastic quality. The amount they stretch depends on the polymer. Ooze Baff makes a wonderful slime like substance, whilst the nappy powder makes a substance like slushy snow.
Most common synthetic polymers are said to be hydrophobic (water-fearing), which means that they do not absorb water. Examples of these polymers might include products such as plastic cups, bags, and plastic toys. There are also hydrophilic, or water-loving polymers. Many natural polymers such as cotton fibres are hydrophilic.
