Lava Lamps

Remember back in the day when lava lamps were popular? Well here’s how you can re-create that fun for the kids in a water bottle.


  • Water Bottle
  • Food Coloring
  • Vegetable Oil
  • Water
  • Alka Seltzer


Fill each bottle about 3/4 full of vegetable oil.  Fill the rest of the bottle with water…but leave about an inch at the top…or it will overflow. Break your Alka Seltzer into tiny pieces and drop them in one piece at a time.



And watch as the magic starts to happen…
Here’s a video that my daughter so proudly demonstrates how this experiment works:
Note: You can put the cap back on the water bottle and save it to use on another day.  Perhaps next time we’ll do this in the evening and put a flashlight underneath the water bottle to make it look more like a lava lamp.
