re: #151 theheat
Well, that certainly puts a different complexion on the matter. I don’t know squat about helium balloons, other than this one is said to have reached an altitude of several thousand feet. What one can lift, and how large it has to be - I haven’t a clue.
How big to effectively launch my neighbor’s cat that craps in my garden? Of that, I’m curious.
Probably two or three times bigger than this one was.
