Yeah, we've all heard that tearful story about a worker dropping a wrench on asphalt and dying of explosion because someone spilled oxygen on it earlier. We tried to replicate that back we were students and even if you use pure tar mixed with porous sand, it just does not explode. It does not even burn unless you ignite it with a blowtorch.
How did we get liquid oxygen? Easy. Just use liquid nitrogen to condense it from air. One large dewar of LN2 nets you about 2 liters of LOX.
