How about hot-air ballooning......?


When you use a helium balloon, why don't you have to heat the gas in the canopy? Dihydrogen is even lighter than helium (it's certainly cheaper); why don't we use dihydrogen for balloons?

And what about air-bags in cars, where dinitrogen gas RAPIDLY fills a balloon in front of the driver in the event of an accident.

And the use of aerosol cans to deliver hairspray or deodorant or insecticide is widespread and ubiquitous. A propellant gas (at increased pressure with respect to atmospheric) is used to force the contents of the can out under your pits.
