Here's an experiment you can try at home. This one is great fun and really messy! Ask an adult to get you some custard.
What you need: PLAIN CUSTARD POWDER WATER
What to do:
Pour some custard powder into a bowl.
Mixit 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.
Thespoon 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!
