Make your own Lava Lamp

I’d like to say thanks to Chasing Cheerios, which is where I first heard about this project. For full instructions, check out Steve Spangler Science.com.

Today Bruce(7), Jenna(3) and I made homemade lava lamps. It was great follow up to our oil spill experiment from last week.

Materials:

  • glass or plastic bottles with a lid (I used mason jars)
  • food coloring
  • cheap cooking oil
  • Alka-seltzer tablets

Directions

  • Fill your jar with about half oil and half water,
  • Add 10 drops of food coloring, or maybe a little less.
  • Then add a little bit of Alka-Seltzer tablet. Don’t add too much or your whole jar might explode!!!
  • Close the lid and watch what happens.

Talking Points for Children

  • Do the oil and water mix?
  • Does the food coloring mix with the water?
  • Does the food coloring mix with the oil?
  • What happens when you drop in the Alka-seltzer tablets?
  • What happens when you close the lid?
  • What do the bubbles do?
