Slime!

Who doesn't love slime?  Easy to make and fun to play with, this is a great thing to do on a weekend.  It does make a bit of a mess, but it cleans up easily. 

How to make:

2 and 1/4 cup cornstarch 

1/2 cup shampoo

Water

Food coloring

Combine ingredients, adding a bit of water at a time to get the right consistency. You can make it as an almost clay like texture all the way to soupy slime. We actually had a lot of playing with it in various textures.
