Non-Newtonian fluids do many amazing things, and here is a great video demonstrating what happens when you fill a pool with a mixture of water and cornstarch.

I knew that. At least, I knew that in an intuitive kind of way. If you ever want to get catsup out of a new bottle, make sure the cap is secure, invert, and smack the cap sharply against the heel of the opposite hand.

Been doin' it for years.

I'm so amazed to learn than Jesus was the first to discover cornstarch.

What do you guys do? Surely not something as big as the pool experiment right?

When you're in kindergarten, anything is scientific - they are exploring the properties of a semi-solid, semi-liquid.
