Solid or liquid?




We mixed 2 cups of cornflour with 1 cup of water.
The paste looked like a liquid.
When we tapped it with our fingers it was quite clear that it was a solid.
We could make balls out of it like play doh, but..............
when we stopped rolling it, it turned back into a liquid and slid through our fingers.
Messy but magic!
