What you'll need:
Vegetable oil (Canola oil would work too!)
Take a clear glass or cup and put the oil in it, I filled our cups about 1/3 of the way up.
Drop a few drops of food coloring in, make them different sizes (I let Evie do this part and she loved it).
The oil drops will retain their shape in the oil. Evie used spoons to mix them up and break them up. She also added more food coloring to each cup and made new creations. She loved it!
