This Science kit bubbles will dive you to discover and learn real experiences, comes with 20 experiments cards, and a manual with 80 subs with a full explanation.

Soft white sugar can increase the viscosity of the bubble, make the thin liquid film of the bubble is not 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 gas causes a lot of foam in the detergent solution, creating ''lava''. The density of water is higher than that of edible oil, so the drops will sink to the bottom of the bottle while dropping into the edible oil. Water droplets are spherical because of the same force around them while falling down. Crystals can look quite magical when they appear from seemingly nowhere in a glass of water. In fact, they form from substances already dissolved in the water. Make your own salt crystal experiment, and learn how it works at the same time. Dishwashing liquid contains surfactants that destroy the surface tension of the milk so that the pigment around the milk will spread and create beautiful animation.
