Making “tie-dye” magic milk is a fun way to experiment with materials you likely already have on hand.
Simply pour some full fat milk into a shallow container (a pie pan works well) and make sure to cover the bottom thoroughly.
Then add several drops of food coloring in various shades.
Now pour a bit of dish soap into a small cup or bowl.
Hand your tinybean a q-tip and encourage him to cover the end in dish soap then dip it into the food coloring.
Tada! Watch the colors magically swirl and “explode.”
