Rainbow Milk Magic
You need: a plate, milk, a few drops of food coloring, dish soap, a cotton swab.
- Pour milk onto the plate so it covers the bottom.
- Add a few drops of different food colorings in the middle.
- Dip the cotton swab in dish soap, then gently touch the milk.
- WHOA โ watch the colors swirl and dance away! ๐
๐ค Why? The soap breaks up tiny bits of fat in the milk, and that pushes the colors around to make a swirly rainbow!

- Put 2 spoons of baking soda into the cup.
- Add a squirt of dish soap and a drop of food coloring.

Walking Water
You need: 3 cups, water, food coloring, 2 paper towels.
- Fill the outside two cups with water; leave the middle one empty.
- Add different colors to the two water cups.
- Fold paper towels into strips and bridge each full cup to the empty middle cup.
- Wait and watch โ the water "walks" up and makes a new color in the middle! ๐
๐ค Why? Water climbs through the tiny gaps in the paper towel. This sneaky trick is called capillary action.

Magic Static Balloon
You need: a balloon, your hair, and small bits of torn paper or a thin water stream.
- Blow up a balloon and tie it.
- Rub it on your hair really fast for 10 seconds. โก
- Hold it near tiny paper bits โ they JUMP up and stick!
- Try holding it near a thin trickle of water โ the water bends!
๐ค Why? Rubbing makes invisible static electricity, which pulls light things toward the balloon like a magnet.
