To do this experiment you'll need: Some plain custard powder Water
Step 1 Put some custard powder into a bowl.
Step 2 Mix it with water while stirring until it feels weird; you’ll know what I mean when you feel it! Try running a spoon handle through the custard mixture.
Step 3 The spoon should leave a clean cut groove that swiftly fills with liquid custard again.Or try sticking your finger in - the custard should stick to your finger!
Step 4 Picksome of the custard mixture up and roll it into a ball between your hands. It feels slimy! If it is not mixed properly, you won't be able to do this.
Step 5 Keep moving it - what happens if you stop? If you keep rolling it the custard forms a solid-like ball, but as soon as you stop...
..it runs away like a liquid. Yes, it is messy, but don't panic. When the mix dries out you can just brush the powder out.
