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.

@Robert Gentel,
I'm so amazed to learn than Jesus was the first to discover cornstarch.

@littlek,
But when grown ups do it, it's SCIENCE

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

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