In your lava lamp, real science is at work!

Oil and vinegar don’t mix because they have different polarities, vinegar is polar (likes water) and oil is non-polar (doesn’t like water), so they stay in separate layers. Vinegar is also denser than oil, meaning it’s heavier for its size, so it sinks to the bottom.

When vinegar (an acid) touches baking soda (a base), they react and create carbon dioxide gas, causing effervescence, what we see as fizzy bubbles!

These bubbles lift the coloured vinegar up through the oil. When the bubbles pop, the vinegar sinks again. That’s the lava effect - all thanks to density, polarity, and bubbling gas.
