http://www.sciencebob.com has detailed instructions for making this easy lava lamp. Chances are you have almost everything that you need at home, so try it out and let us know how it goes. We used fizzing antacid tablets that go by the brand name alka-seltzer here in the US. I'm not sure what they may be called in other countries. Have fun!

  • is the alka-seltzer in singapore asia?

  • To make an easier lava lamp... get a cup, fill it up with water half way, add any type of oil so the whole mixture has filled the cup 3 quarters of the way. Then add some food colouring. then add table salt!!! simple as that! and if you want to make even more realistic... put a lamp over it!
