Soap Foam Rain Cloud Experiment

A clear jar or tall glass

Water

Shaving cream

Food coloring (blue, purple, green work best)

Small cups for mixing colors

Droppers or small spoons

Fill a clear jar three-quarters full with water.

Spray a thick layer of shaving cream on top — this is your cloud.

Mix food coloring with water in small cups.

Give your child a dropper and let them drip colored water onto the cloud.

Watch carefully — the color soaks into the foam, then breaks through as colored rain.

Keep adding colors. Different colors create different rain streaks inside the jar.

Ask: "Why does the color come through? What happens when the cloud gets too heavy?"

This is a real analog for how rain works: clouds become saturated with water vapor, and when they can't hold more, rain falls.

Use a clear glass for the best viewing angle. Seeing the rain streaks from the side is the dramatic moment.

More shaving cream = slower rain. Less = faster. Experiment with cloud thickness.

The visual is genuinely beautiful. Slow-falling color streaks through water look almost artistic.

Try warm-colored "rain" (red, orange, yellow) for a sunset storm effect.
