[Presto]

the blob jump is when one person jumps on one end of an inflatable pad to catapult the other person who's lying on the other end

I'm not sure why, but before clicking play, i was expecting some sort of mass blob jump. I had pictured a massive inflatable pad with dozens of people on it getting launched into the air.
But after clicking play and watching that video, i realise just how seriously messed up dozens of people would get if they all got launched at the same time like that. HUGE air!!! The hangtime that guy got was pretty nuts!
