Is hydrogen really that dangerous in small quantities? The Hindenburg had seven million cubic feet of the stuff, and half the passengers still survived.

- wvenable 10y agoWe tested this in science class -- a balloon sized quantity of hydrogen makes a very forceful explosion. Safe enough to be used in the middle of a classroom but not something you'd want small children carrying around.
- gozur88 10y agoSure, it makes a "very forceful explosion" when confined. It's not the same scenario, though.
- wvenable 10y agoThe context of this discussion was "hydrogen balloons" so that is the same scenario literally.
- gozur88 10y agoYou put it in balloons in science class, and not in a test tube?
- wvenable 10y agoYup. Chemical reaction to create hydrogen and had it fill a balloon over lunch. One of the other students got to explode it with a match taped to a meter stick. I could feel the air rushing by when it exploded. It was also quite loud but no big fire ball or anything.
