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.
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.
We should go back to filling them with hydrogen.
What could go wrong?
I mean other than that…
wasn’t that just the flammable lining?

Am I missing a joke? Airships used hydrogen gas
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.

I’m not sure you could do that in schools today.
