How to make a candle flame jump through the air
In short: Discover the science behind a seemingly magical trick where a flame leaps from a lighter to a wick. This experiment explores the invisible gases that keep a flame alive.
The video demonstrates how a blown-out candle wick remains hot enough to continue drawing up wax. As this wax evaporates into a gas, it creates a flammable vapor that can be reignited, making the flame appear to jump.
The experiment also investigates the role of oxygen in combustion. By covering candles with jars of different sizes, the presenters show that larger jars contain more oxygen, allowing the chemical reaction between wax gas and oxygen to persist longer before the flame eventually goes out.
