Relight a Candle with Smoke! Video Watch time Under 1 minute December 4, 2024 Image Do you know how to re-light a candle without touching the match to the wick? In this video, Alex Dainis explains how you can reignite a recently blown out candle by touching a match to the stream of smoke! Candles burn when the heat from a flame vaporizes the liquid wax, breaking it down into carbon dioxide and water, as well as releasing heat. The smoke from the recently blown out candle contains vaporized wax and other unburned particles, so when a flame touches the smoke it can travel down the stream to the wick, breaking down the unburned particles on its way!
