When I was in school decades ago, my science teacher brought in a big balloon filled with hydrogen and lit the string on fire without telling us that it was filled with hydrogen.
I could feel the explosion in my bones. It was neat.
I’m not sure you could do that in schools today.

I mean other than that…

Would make for more exciting birthday parties.

Seems more like a gender reveal party sort of thing.

The alternative is to use extremely limited quantities of gas crucial for MRIs, chip making, metallurgy, and a few other high tech applications. But hey, pretty balloons.

Only a matter of time before they can’t get any because we wasted such a limited resource on vanity instead of the pursuit of science.

When I was a kid, Dave Berry had a column where he made fun of the US Strategic Helium Reserve. This taught me an important lesson. When people make fun of what seems like government waste, 75% of the time it turns out to be really important. Not always, but you should look into it more.

Yeah, there’s areas where it’s surprisingly hard for laypeople to tell apart “mostly useless” and “saves lives on a daily basis”.

Am I missing a joke? Airships used hydrogen gas
Blaster_M@lemmy.world 5 months ago
Specific airships made by a specific country that had no access to helium…

Not exclusively, hydrogen being lighter and cheaper meant it was still sometimes used when helium could have been.

wasn’t that just the flammable lining?
