Rainbow Milk Fireworks
What you need
- Whole milk
- 4 colors of food coloring
- Dish soap
- A cotton swab
- A shallow plate
- Pour milk into a shallow plate until the bottom is just covered. Whole milk works best.
- Drop four colors around the plate, spaced apart. Do not stir.
- Dip one cotton swab in dish soap and touch it to the center of a color. Hold it there, then try a new spot.
The scienceThis is surface tension, and soap is what breaks it. Water molecules pull on each other hard enough to act like a skin across the surface. Soap has one end that loves water and one that hates it, so it wedges into that skin and the tension releases unevenly, yanking the whole surface outward and dragging the color with it. Your kid has already seen this: it is why greasy dishes finally let go the second the soap hits, before you have scrubbed anything.
