Mix the flour and salt together, then add the water and stir. It should be the consistency of a slightly thinner pancake mix.
Split the "batter" into as many bowls as you need for the number of colors you want.
Once the batter is split into the bowl, add the food coloring and mix.
Add the colored batter into the squeeze bottles and put on the lids OR pour the each of the colors into their own ziplock bag.
Once the designs are finished (ours was a pumpkin with stem and leaves), pop it in the microwave for about 30 seconds. POOF! It's puffy!
If there is a loooooot of paint on your paper, you may need more time in the microwave.
