Homemade puffy paint

We made homemade puffy paint on Tuesday and the girls had a BLAST with it!  I think I need to find more activities like this because they could have painted forever I think!  They weren't too excited about taking pictures this time...but I took a few (too busy to edit them today) anyway!

Homemade Puffy Paint
1 tablespoon cornstarch
1 tablespoon salt
Food coloring
enough water to make a paste (I added too much)

***Paint on cardboard with Qtips and then microwave when you are done for 10-30 seconds on high
