Lava Lamp Experiment

Making temporary lava lamps is a fun, colorful and easy science experiment sure to keep your kids engaged. You’ll need a tall empty jar or bottle and some common household products. There are two ways to do this:

Baking Soda Lava Lamp

  1. Put a few tablespoons of baking powder into your jar.
  2. Add water (about one-quarter of the way up the jar).
  3. Add a few drops of food coloring (we found out that cake decorating gel works well too!)
  4. Swirl ingredients.
  5. Pour in vegetable oil until the jar is three-quarters full.
  6. Pour in a little bit of vinegar (start with a tablespoon and add more as needed)
  7. Watch the lava lamp activate!

Antacid Lava Lamp

  1. Fill the jar about half-way with vegetable oil.
  2. Add a bit of water so that jar is about three-quarters full.
  3. Drop in some food coloring.
  4. Break and antacid tablet into several pieces.
  5. Drop the antacid pieces into the jar one at a time.
  6. Watch the lava lamp activate!

Safety Tip: Do NOT put the top on your jar or bottle while the mixture is active and bubbling!

Add Fun! Do this experiment in a dark room and put a flashlight or other light behind the jar for an extra groovy experience.
