First, add 1/4 cup of glue and 1/4 cup of shaving cream into a ziplock bag.
Add as much food coloring as you want to the mixture and seal the bag, making sure to get out as much air as possible. Otherwise, there might be some extra clean-up if the bag pops open in the next step.
Now for the fun part! Let the kids squish and squeeze the bag to mix all of the ingredients together.
Repeat steps 1-3 for each color of puffy paint you would like to make. Get creative with the colors - mix two colors, add more or fewer drops of coloring to create pastels or bright colors.
Squish all of the puffy paint to one bottom corner of the ziplock back and snip off a tiny bit of the bag. The bigger the hole, the more puffy paint...so start with a small snip and cut more off as needed
OR: Snip off a larger portion to squeeze into a plastic bottle.
