Custard Gone Crazy
Is it a solid? Is it a liquid? No, it's a scientist's favourite trick!
What you need
You should be able to find all of these items in your house.
What to do
2. If you increase the amounts of custard and water, you could (in theory) fill a paddling pool with the mixture, and run across the top without falling in. (If you do this you can jump up and down, but when you stop jumping you sink into the mixture. To remove your feet pull gently or you may be stuck there for good!)
When you move the custard mix around slowly the custard powder particles can move around in the water quite freely, and so it acts as a liquid. When you move the mix faster or hold it in your hand tightly, the solid particles rub against each other causing friction. This makes them stick together and act like a solid.
