This is a video demonstration of 'The Conflicted Candle', a machine built by engineer James Cochrane that repeatedly lights a candle then extinguishes it approximately 15 seconds later. For reference, that's significantly faster than I extinguished the candles downstairs last night, because they were still burning when I woke up this morning. I hate it when that happens, even when they don't start a fire. I mean, candles are expensive. At least in stores. Honestly I've found the best deals on candles are in friends' guest bathrooms.
Keep going for the video.
Thanks to Danby, who agrees fires were meant to burn.
