I've always wondered when I let go of a balloon, where does it go? Does it go so high that it pops, leaving it's rubbery shell to fall? If so, I want to be walking around one day, and have one fall right into my path. I think that would be a great moment.
From the looks of this video, there are hundreds and hundreds of great moments to come.

cool! I've always found the sight of balloons floating off into oblivion really frightening for some reason - as if it reminds me of our own fragility-ness or whatnot, like we could all just float away too at any moment. Wow!
