Solid or Liquid?

I remember when I took a babysitting class when I was 12 years old at our local 4H center. The class taught us basic skills for watching children & also gave lots of activities to entertain kids. I remember one in particular: corn starch & water. Beware!! Super duper messy. Tons of fun, though! Abigail had a great time playing with this texturably unexplainable medium. I'm not sure of the proper measurements, but you mix the cornstarch and water until it's kind of solid, kind of liquid. Helpful, huh? Seriously, it makes for a fun afternoon!
