Walking on liquid

This past weekend was the first USA Science and Engineering Festival. How lucky are we that we can just take the metro in and "celebrate science at over 1500 fun, hands-on science and engineering activities?"

We made inheritance bracelets (Daddy Geek and Geek Girl can both taste PTC); used maggots to spread paint around and create works of art; used licorice, toothpicks, and marshmallows to model a DNA molecule; built a catapult; and had to drag Geek Girl away.

The highlight of the day was running across a non-newtonian fluid -- if you step on it slowly you'll sink, but if you run across it, you won't.

Geek Girl will demonstrate.
