This science kit about bubbles will allow you to discover and learn through real experiments. It comes with 20 experiment cards and an 80-page manual with complete explanations.

Soft white sugar can increase the viscosity of the bubble, making the thin liquid film of the bubble harder to break and creating a tight seal around the air inside. 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. This carbon dioxide causes a lot of foam in the detergent solution, creating "lava." Water is denser than cooking oil, so drops will sink to the bottom of the bottle, whereas they fall into cooking oil. Water drops are spherical because they experience 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. Try experimenting with salt crystals and learn how they work. Dishwashing liquid contains surfactants that destroy the surface tension of the milk so that the pigment around the milk spreads and creates a beautiful animation.
