Materials
Directions
1
Squeeze drops of food coloring into a dish of milk.
2
Squeeze some dish detergent into a small container.
3
Dip a q-tip in the dish detergent, then dip it into the milk. See what happens next!
You can also squeeze the dish detergent directly into the milk and just swirl with a q-tip, if you prefer. Play around with colors and methods to see which produces the most fun results!
