When you blow out a candle, you can re-light the wick using the smoke trail left behind. This is a topic we’ve discussed before, but I’m thrilled to finally see the process in true high-speed, thanks to the Slow Mo Guys. The plume that rises from the extinguished candle is an atomized mixture of fuel (wax) and air. When you bring a new combustion source–the match–close enough, that mixture ignites and the flame spreads downward back to the wick. (Video credit: The Slow Mo Guys)
