DIY STEM Project For Kids: Lava Lamp Experiment

In this video tutorial, the teacher demonstrates how to create a lava lamp effect using a glass, vegetable oil, water, food coloring, and Alka Seltzer tablets. The process involves observing the interaction between oil and water, adding food coloring, and using Alka Seltzer to create bubbles and a lava lamp effect. The teacher explains the science behind each step and encourages viewers to try the experiment themselves and share their results.

How do Alka Seltzer tablets contribute to the lava lamp effect?
