Hitting jello (or as they call it, "jelly") with tennis rackets is the latest stroke of genius from Gav and Dan, the Slow Mo Guys.  But it's not the first – we've been obsessed with these guys and their videos for a long time. Of course, no one can forget the man in a giant water balloon, but since then they've also entertained us with their pyromaniac-friendly match head bomb and water on a grease fire videos, as well as the delightfully cringeworthy taser on bare skin. But this latest entry is uniquely satisfying for people who love watching goo get smashed (everyone).
