I have been subscribed to these guys for some time, they have amazing videos and are totally worth checking out. Brady Haran (the guy holding the camera) has a bunch of channels with equally amazing things that are also worth checking out. Professor Poliakoff is awesome too, love the hair.

This is totally not an advertisement lol, just a testament to how awesome Brady's videos are. (I suggest Numberphile)

Liquid O2 is the condensed form of the stuff that's in the air, really cold, like -170 C. You can soak cotton in it, ignite it and have it explode. Fun stuff, if slightly dangerous. Also used in rockets.

Yea that's what I thought, so how come it didn't ignite / explode when the charcoal was on fire in it ?

Kinetically limited reaction, LO2 is at -170ish, most chemistry is slow at that kinda temp. Hard to explain on a computer forum...
