Supplies:

Directions:

  1. First, add 1/2 cup of water to the small plastic containers.
  2. Next, add a few drops of food coloring to the water then mix. Use two different colors to make more than one lava lamp. I love using these gel food colors because of the vibrant colors.
  3. Fill each glass 3/4 full with vegetable oil.
  4. Pour the colored water into the oil, being careful not to fill the glass too much.
  5. Finally, add one or two Alka-Seltzer tablets to each glass container then watch the chemical reaction. *DO NOT let the kids put the tablets in their mouth.*
The Alka-Seltzer tablets react with the water to produce carbon dioxide gas bubbles! These stick to the colored water droplets. The water and gas combination is less dense than the oil, so they rise to the top of the glass! How cool is that?! Keep adding more tablets to the container so the fun doesn’t end. Enjoy!
