3.    Add about 1tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.

grandpa’s thoughts:

So, you're going to be the hit of the party when you make Elephants Toothpaste. But be warned it's messy and you're going to need to have extra ingredients so you can do it over and over and over and over and over again. Be cool grandpa!
