In honor of 4/20, just in case you don't have your own lava lamp sitting around, here's a way to make one on the cheap!

eBaum's World put together this little easy to do "science" project for you for 4/20.

It looks simple enough. All you need is:

  • Cooking oil
  • Vase
  • Food Dye
  • Alka-Seltzer
  • Water

Basically, all you do is put the food dye in the water, and mix it up. Pour the water into the vase. Fill the rest of the vase up with cooking oil, and drop the Alka-Seltzer into the vase. VOILÀ!
