I was watching a show on sea snakes last night and this particular sea snake being of terrestrial origin can't lay it's eggs in water. So it lays them in this underwater cave. The neat thing about the cave was that a fog or cloud was generated when the waves created high and then low pressure variations. It reminded me of this plastic bottle demonstration.

"A better understanding of the surface properties of liquid could help with industrial processes, acoustics, and liquid fuel rockets." And maybe jam jars and snorkelers too.

Most demonstrations like this talk about the triple bond energy of acetylene. I had a shop teacher do this one for our chemisty class in high school. And yes it was loud.

But I kind of like this one too. One time I sprayed pure oxygen into my little Logan pulsejet with some methanol coating the insides and lit it. I about went deaf. I think though this demo is probably hydrogen and oxygen or maybe methane and oxygen, if that would be light enough. Still though, the effect is roughly the same. Note the balloon appears lighter than air.
