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鈥檒l 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
Pick some 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.
听
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.
