Any Aussie welders here? Just got done seeing Danny Deckchair, where a bloke in Sydney floats away on a deckchair and a bunch of balloons. Hours later he’s accidently shot down by fireworks and has adventures in the small town he finds himself in. On the goofs page it’s asserted that, being filled with helium, the balloons shouldn’t have exploded when the fireworks struck them. I noticed that in the scene and thought, “Huh. Must have been filled with hydrogen.”
So, after all this exposition (pant, pant) comes the question. The gas bottles Danny and his mates were filling the balloons with were tan. Hydrogen or helium?
