How It's Done:
When a cloud (which is made of tiny drops of water) accumulates too many drops, it releases the excess moisture in the form of rain. The same thing happens to the shaving cream; at a certain point, it can't absorb another drop. That's when gravity steps in, pulling the colored water through the foam to create a downpour below.
The Skills It Builds: lab techniques, fine motor control, earth science
Did you know? This experiment lets kids practice pipetting, a laboratory technique for transferring liquids drop by drop. A scientist would use a glass tube (called a pipette). We used a plastic straw.
