All you need is a matchbox, a small candle, a light plastic cup, and thread to create this incredible physics demonstration! 🔥
This setup shows how heat transfer by convection works: the candle flame heats the air inside the cup, making it less dense than the surrounding cooler air. This difference in density creates buoyancy, causing the cup to rise and float.
Science doesn't have to be complicated! Always ensure a responsible adult is present when working with fire.
Setup: The cup is lightly suspended over the flame by threads attached to the candle/matchbox base.
