It makes a wonderful display of fire chasing fire, that’s what happens. The best science experiments always result from eager amateurs messing about.
This is an awesome experiment, and one with results which I didn’t foresee. I thought the whole thing would go whoosh, up in flames, but science knows different.
Apparently, as the maker of the video explains, the foam bubbles release flammable vapours as they pop, meaning a flame can’t be sustained in just one of the ring.
What I want to know is how this guy discovered it, and what made him think of setting light to a circle of mousse? Also, how did his wife react to him doing it on the dining room table?
