Coordination World Records

Hugo VanEvery snapped the fingers of his left hand 16 times in seven seconds while his right hand kept making the same snapping motion without letting a snap ring out, a brain-teasing coordination trick he filmed at his desk in a classroom in La Grange, Illinois. RecordSetter counted the snaps on the audio of his continuous, unedited clip, crediting only the ones that ring out clearly, and all 16 land inside the seven-second window. Try it yourself: getting one hand to snap while the other deliberately fizzles is harder than it sounds.

Nate T. completed 342 repetitions of a push-up and juggling medley.
