Here’s the classic science experiment of mixing fire and alcohol in a large empty jug. It’s always fun to see the perfect layer of flames slowly dance its way down the cylinder, like a slow drip of fire as the alcoholic vapors combust. Of course, the best part is that ‘whoosh’ sound it makes.
The simple flame is an extraordinarily complex phenomenon, one that involves thousands of chemical reactions. But fire also plays off the effects of gravity. So what happens when you take that gravity away? As a recent experiment aboard the ISS has shown, you get a very strange flame, indeed.
