🦸 Myth busters for this topic
❌ "Boiling water bubbles are made of air."
✅ The bubbles in boiling water are water vapour — water that has changed into a gas.
The bubbles rise from the bottom where the water is hottest, showing water turning into gas throughout the liquid.
Try it yourself: Boil water with adult help and watch the bubbles form from the bottom — they are water in gas form, not air.
