This bubble science kit will let you discover and learn real experiments. It comes with 20 experiment cards and an 80-submenu manual with a complete explanation.

Soft white sugar can increase the viscosity of the bubble, so that the thin liquid film of the bubble isn't easy to break, and wrap the air inside tightly. White vinegar is acidic and baking soda is alkaline. When the two are mixed, a chemical reaction occurs that produces a large amount of carbon dioxide gas; this carbon dioxide causes a lot of foam in the detergent solution, creating "lava."

The density of water is greater than that of cooking oil, so the drops will sink to the bottom of the bottle as they fall through the cooking oil. Water drops are spherical because they are subject to the same force as they fall. Crystals can seem magical when they appear out of nowhere in a glass of water.

In fact, they form from substances already dissolved in the water. Do your own experiment with salt crystals and learn how they work at the same time. Dish soap contains surfactants that destroy the surface tension of milk so that the pigment around the milk spreads and creates a beautiful animation.
