Here follow my instructions to make your own lava lamp experiment. This experiment will not take long and you only need things you likely already have in your kitchen. Lava lamps are fascinating, aren’t they? I love to see the bubbles rise up through the glass.
Remember to start the experiment with a hypothesis, what do you think will happen?
Instructions for parents: Read this first.
Water and oil don’t like each other (it is called polar and non-polar substances) and will therefore not be mixed, but instead, fall into two layers. The water weighs more than oil and that is why the water settles at the bottom. When the effervescent tablet comes into contact with water, carbon dioxide, which is a gas, is released. Gas weighs less than water and oil, so the gas will rise to the top.
