The word cryogenics gets my imagination going! Per Wikipedia, It means “the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures“. When I hear it I think of human bodies being frozen until a cure for the disease they are dying from has been found and I think of science fiction books where the characters are frozen for a long, long space voyage.

I found an interesting article on cryogentics here http://abcnews.go.com/Health/life-ice-world-crazy-cryogenics/story?id=14167348#.TwuZh1auHTo.  The article states “And for approximately $30,000, anyone can be cryogenically frozen. Currently, there are over 200 people in a frozen state at cryonics centers in the U.S. – and some 2000 people have signed up for it.”

Cryogenics is the word printed on the large canister at Pacific Welding Supplies, 2902 S M Street, Tacoma, WA 98409. I suspect that the canister is most likely used for the gases involved with industrial welding instead of human preservation or space travel, but still its fun to consider the possibilities!
