This is just insane. Seriously watching this video made my palms sweat. Leave it to some crazy French guys to try and walk a slack-line between two hot air balloons. Oh and there is a clown, yes a clown in the video that ads to the scary factor. Yes, clowns are scary. If the ballon video below doesn’t scare you, and you want to see more high-wire acts, they have a documentary you can watch on Vimeo here.
