Add 3 cups of shaving cream to a bowl.
Pour in a 1/2 cup of glue.
Stir in a 1/2 teaspoon of baking soda.
Add a few drops of food coloring and stir well.
Slowly pour in 1 tablespoon of saline solution while stirring.
If the slime is really sticky, add in a little more saline solution and stir.
Squirt some saline solution onto a mat and knead the slime on it.
After kneading for a couple of minutes, the slime should be a good consistency.
