Finding: BUSTED

Explanation: Many have tried — and most have failed — the ultimate playground trick of completing a 360-degree revolution on a run-of-the-mill swing set. Joining those schoolyard stuntmen, MythBusters Kari Byron, Tory Belleci and Grant Imahara pushed and pumped in an attempt to ace the full swing.

But harnessing enough rotational centripetal force on your own to overcome gravity's downward pull is simply impossible. None of the trio could crest the top of the swing set, much less sail all the way around it. Even a foursome of Hell's Angels, who stepped in at the MythBusters' request, couldn't propel a 65-pound (29.5-kilogram) dummy completely around the circular voyage.

Slow motion footage showed the swing chain slacking at around the 300-degree mark, busting the myth and saddening schoolchildren everywhere.
