All you need is a matchbox, a small candle, a light plastic cup, and thread to create this incredible physics demonstration! 馃敟
鈥婽his 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.
鈥婼cience doesn't have to be complicated! Always ensure a responsible adult is present when working with fire.
鈥婼etup: The cup is lightly suspended over the flame by threads attached to the candle/matchbox base.
