yes but back in the 20's and 30's they used to fill kids ballons with
hydrogen and the kid or the lucky lady that her gent bought her a
balloon ,would be walking along until some prankster would have a lit
cigarette and touch the balloon
and have a nice pop go off ,never hurt anyone but it was a scare ,after
WW2 they replaced hydrogen with helium and the pramksters had no more
fun
