DIY Lava Lamp

Ingredients

  • A clear plastioc bottle or mason jar
  • Water
  • Vegetable oil 
  • Alka Seltzer Tablets (generic is fine)
  • Food coloring

Method

  1. Fill the bottle up about 1/4th (1 quarter) with water.
  2. Pour the vegetable oil in the bottle until is almost full. You may want to use a measuring cup with a spout or a funnel. You may have to wait a couple of minutes for the oil and water to separate.
  3. Add a few drops of your favorite food coloring. Watch as the color sinks through the oil. Did your drops of color mix with the water immediately or float in between for a few minutes?
  4. Break your fizzy tablet in half and drop part of it into the bottle. Get ready … here come the bubbly blobs!
  5. You can even get a flashlight, turn off the lights and drop in another half tablet. This time shine the flashlight through the lava lamp while the blobs are bubbling!
