I found this fun idea on Pinterest and thought it would be something my kids would love. And indeed they did. Simple art, science and fun all rolled into one! This is what you’ll need to make Magic Milk Paint.
Toothpick or bamboo skewer
Pour your milk into a small dish with a lip. We used some Tupperware container lids and it prevented (most) spills. We used almond milk because it was nice and thick (the original called for whole milk). I think if you use skim milk that the colors won’t be quite as spectacular.
Add a variety of food coloring drops to your milk dish. Dip the “magic” toothpick into dish soap and let your kids tap it onto one of the food coloring drops. The soap will disrupt the surface (intelligent-sounding scientific term: reduce the surface tension) of the milk, pushing the color away from the toothpick.
Continue to dip, allowing the colors to swirl together.
Eventually the milk will turn a lovely blue-green color and then you can start all over again with fresh milk! Good times!
