Congratulations! It's an Escape Artist!

The very first sad thing about this video is that you knew it was going to be a gender reveal stunt without having to be told. In order to hide whatever is inside, the balloon had to be heavy duty. So it made no sense to whack at it with bats instead of poking it with pointy things. But they whacked away until the mooring gave way. What now? Chase it, of course, to the point of falling on your butt, even though the balloon was already quite out of reach. (via reddit)
