What does it teach?

Learn how water molecules work and what the soap in bubble solution does to decrease the surface tension of water so the bubbles can stretch and float away without breaking. Discover how glycerin helps water to stay in the bubble, causing them to last longer.

Experiment

Ideal conditions for making massive bubbles:
Make bubbles in the shade, rather than the sun.
Make bubbles on quiet, rather than windy days.
Play with your bubbles after a rainfall; if the air is full of moisture, your bubbles will last longer.
