How Does a Candle Burn in Space?

A candle burns differently in space because there's no gravity to pull the melted wax down. On Earth, gravity helps the flame grow tall and round, but in space, the flame becomes small and blue. It’s like lighting a tiny, glowing star inside a bubble.

Examples

A candle burns like a tiny blue ball in space, unlike its long, yellow flame on Earth.
Floating in zero gravity, the wax from a candle forms little bubbles around the flame instead of falling down.
The flame doesn't reach as high in space because there's no gravity to pull it up.
