DIY Bathtub Paint
Kick bath time up a notch
Materials
1 cup dish soap (something your kids won’t have a skin reaction to)
1/2 cup cornstarch
1/2 cup water
Food coloring
Directions
In a sauce pan, mix the cornstarch into the cold water until it is dissolved—it should still be a bit pasty, but not clumpy.
Turn up the heat and bring the cornstarch water to a boil – stir constantly to make sure there are no chunks.
Add the soap and mix, heating on medium temperature until just boiling. The soap should have a gel-like consistency as it cools.
Add food coloring.
Store your paint in an airtight container. The paint will separate slightly when stored, stir well before use. Test the paint on a patch of your tub to ensure that your food coloring does not stain
