Glow in the Dark Lava Lamp: Science for Kids

  • Vitamin B-12
  • Blacklight
  • Vegetable oil
  • Alka Seltzer tablets
  • Jar or beaker

Add some vitamin B-12 powder to about two or three tablespoons of water. The water should turn a yellow-orange color. Pour this liquid into your jar or beaker and fill the rest of the container with oil.

Take the jar into a dark room, but try not to spill it or you will have a disastrous mess.

Shine a black light on the jar to light up the water. Vitamin B-12 has a natural luminosity that is perfect for this project, but you can also use the inside of a highlighter marker or a glow stick if you don’t have any B-12.

Children will be absolutely fascinated with this experiment, even if they’ve done it before. Something about glow in the dark will please kids every time.

THE SCIENCE LESSON

Ordinarily, oil is lighter than water, which causes it to stay above the water. But when Alka Seltzer tablets are added to the water, they create a reaction that releases carbon dioxide. This is even lighter than oil. When the gas bubbles rise, they take a bit of water with them in glob form, which rises to the top and causes bubbles to form. The bubbles then float back to the bottom of the jar once the gas is released and reaches the top of the oil. This experiment can be repeated until you run out of Alka Seltzer tablets.
