You have 2 candles, and you light them both. You then hold them like handle bars, but you put one above the other (flames above eachother, but not touching at all). Then you blow out the top candle, and without touching the flame on the bottom candle, the top candle relights.
I assume it's either oxygen or carbon dioxide or something, but I'm just looking for clarification so I don't look like a dumbass. And don't laugh at me, it's only 7th grade science
