Cornstarch and Water Mixture

Water molecules go in between the starch molecules....
Vocabulary: colloid(s); suspension(s); solution(s); matter; molecules


Spangler does the "walk" across a cornstarch mixture tub on Ellen!
(Ellen Degeneres, February 13, 2008)

He tries to talk Ellen into it, but, a member of the audience does it instead...Ashley from LA.

Advice: Go fast. If not, you sink. (Spangler shows how!)

Ashley goes back and forth... She has fun and doesn't sink.

It's a lot of cornstarch!

So, what is the science?

The Key Conundrum episode of the Big Bang Theory (Television program, airing on or about 10-6-08, which parents and caregivers may want to watch before or instead of sharing with children as there is a lot of grown-up innuendo) has a small portion on using cornstarch and water: http://community.tvguide.com/blog-entry/TV-Show-Blog/Big-Bang-Theory/Episode-Recap-Barbarian/800048013 Sometimes they do not show the whole episode.
