4 months agoIt’s a common high school chem lab demonstration. Without added oxygen, the H2 balloons sort of burn from the outside in, and you get a sort of slow burning mushroom plume. It could light paper or cloth on fire in close proximity.
With added oxygen… BLAM! It could shatter windows.
I lived in Burbank for a decade, and drove by the water tower a couple days a week.
Oh how frequently I wished they would come bouncing out.
