Discover density, polarity, and the science behind producing gas bubbles in liquid with the Discovery Glowing Bubble Light! Begin by filling the provided container with water and oil from home, then drop the tablet inside. See density in action as the tablet dissolves — it releases carbon dioxide into the solution, which forms tons of bubbles that bounce up and down! Follow the scientific method as you hypothesize, test, and observe — how can different temperatures or the number of tablets added affect the movement and action you see inside the container? Switch on the LED light inside the lamp for a super cool glowing bubble show! This hands-on STEM kit features 7 different experiments for little scientists to try — and even bonus exploration activities to inspire them to keep experimenting with household materials. Package design may vary. Recommended for ages 12 years and up.
