hey try this
First you need to start off with equal cornstarch and water. And a big bowl to mix it up in. Now if you want to make fun colors I suggest putting a drop of two of food coloring into the water before mixing. Pour both water and cornstarch in the bowl and start mixing. The goal is to mix it until it runs off the spoon easy. Add small amounts until you get a runny consistency. from-http://baconinmypocket.blogspot.com/2012/08/its-fun-word-to-say-and-keeps-kids-busy.html
