Ooblek

Everyone needs to make ooblek at some point in time. It behaves very strangely. If you play with it slowly, it behaves like a liquid and if you play with it quickly, it behaves like a solid. So you can't punch your fist into it, but you can dip your fingers into it. You can pick up a handful of it only to have it melt between your fingers.

Add water to the corn starch. You need more corn starch than water but we tweaked it a little because we weren't sure about the consistency. In the end, the water evaporates and your mixture gets thicker over time. 

It was difficult to stir. We added blue food coloring.

We played with it on and off all afternoon and it ended up making a huge corn starchy mess in my kitchen but it was worth it. It was really weird stuff.
