Measure 3 cups of foamy shaving cream into a large bowl.
Stir in enough food coloring to get the color you want.
Add the glue and stir in well.
Add the baking soda and saline solution.
Fold it in really well until it pulls away from the sides of the bowl and forms a blob.
If it is still too sticky, put a few drops of saline solution on your hands and knead the slime.
