We are investigating materials.
Today we were talking about solids and liquids.
We know that solids are usually hard but liquids are easy to pour.
Water is a liquid and cornflour is a solid.
What happens when you put some water into cornflour?
It mixes like custard but is neither a proper solid nor a proper liquid.
It looks like a liquid and it spilled like a puddle onto the floor
BUT
teacher could pick the puddle up like a solid!!!
When you poke the liquid it feels hard like a solid but when you just leave your finger in it your finger sinks through it like a liquid.
If you had a big enough bath you could even run across it!!!
Have a look:
