How to Make a Lava Lamp: DIY Science Experiment

Homemade lava lamps teach kids everything from Science to design in Art, look seriously cool and are so easy to make!

What’s more is most if not all of the ingredients are found in the kitchen cupboards.

Below are two EdHacked videos (YouTube & Facebook) showing you how it’s done.

What you’ll need:

So, how does it work?

The last thing teacher or parent want is to be asked the age-old “But how?” and not know.

So why are homemade lava lamps such a good lesson anyway? It teaches kids a great deal on forces & mixtures. The cooking oil stays above the water because oil is lighter – the two don’t mix either, so perfect for this experiment. We add the food colouring to see how they don’t mix, better – and because the reaction is pretty to look at.

When you add the tablet, it creates gas in the form of bubbles. These bubbles rise through the oil to the top. The water then sinks back down to the bottom, underneath the oil!

Curriculum:

  • Science – Forces, Materials and Change, Design & Make
  • Art – Design & Make, Mixing.

Extensions/Repeat experiments –

    • What happens if I don’t break up the tablet?
    • If I use Burocca/something else as the agent, does anything change?
    • What happens if I put the lid on/off?
    • If I shake the bottle?
    • Does the size of the bottle, or type, matter?
    • Does food colouring matter? Or how much oil/water we add?
