Sarah and Nick played with their awesome science kits they got at Christmas. They had a ball making ooze. Take parts water and corn starch and mix with your fingers. Add some food coloring if you want to be a bit more colorful. It makes a really cool ooze. It will drip from your fingers, but if you grab it, hit it or something like that, it instantly turns hard. Release the pressure and it will go back to a liquid like consistency. OK, so I admit it. I thought it was cool too.
