Making and playing with Liquid Oxygen

[@theCodyReeder]

+Nile Red About that whole never bringing it near grease or flammable oil thing... lol oh and btw liquid oxygen is denser than water ice so the water should float, I.e those white specs suspended in the liquid were actually solid argon. which menes that you were getting a lot of air into the test tube.

We eventually descended into throwing gloved handfuls of it at each other when the other guy wanst looking. You know, as a prank. Because it stung really bad for a split second. Eventually, we triggered the alarms that warned of explosive levels of oxygen gas in the building, and caused a full scale evacuation of the entire facility, requiring not only the entire county fire department, but also a bomb squad to be called in.

I remember a "magic with chemistry" show when I was young, in which the demonstrator soaked a cigar in liquid O2 and then lit it. It burned like a flare. In another demo, a wad of foam rubber was stuffed into a metal tube which was closed on one end, then soaked with liquid O2 then ignited. The foam did a mild explosion and burst out of the tube... fun stuff. Unfortunately when the same demo was done a few years later, the tube shattered, sending shards of metal flying. One youngster in the front row of the auditorium was hit in the eye, IIRC. One might speculate that when the metal was supercooled it became brittle, and years of being used for that demo left it cracked and weakened. That particular item was removed from future "magic with chemistry" shows.
