Glad you asked...
Slime is very easy, and nasty, to make. The first step to making slime is to go and buy all of the ingredients that you will need. Make sure you get green food coloring.

Then again, this answer might help you...
To make slime heat one part water in a saucepan. Pour the heated water into a bowl and add food coloring. Add two parts cornstarch a little at a time. Blend the mixture until smooth and add more cornstarch slowly if the slime is too runny. Keep the slime in a zip-top bag to make sure that it stays moist.
