Hi Lauriane,
Making an Alka-Seltzer Powered Lava Lamp is a really simple and fun activity! To do this activity, you only need empty bottles, hot and cold water, food coloring, vegetable oil, and an alka-seltzer tablet. From there, you can follow the instructions and see your lava lamp in action!
Have fun with this project,
Carissa
