One Hand World Records

Yanhao Deng of Chenzhou, Hunan, stood up five square plastic bottles in 5.24 seconds using only one hand. The bottles start lying on their sides in a row in front of a phone stopwatch propped against the wall, and the same hand starts the clock, sets each bottle upright on its base, and stops the clock once the fifth is standing. RecordSetter read 00:05.24 on the stopwatch close-up, matched it to the gap between the two taps on the video, checked that the stopwatch was reset to zero before the run and that no second hand touches a bottle, and watched all five stay standing on their own for several seconds after the stop. Five bottles, one hand, just over five seconds.

Yanhao Deng of Chenzhou, Hunan, rolled two D batteries around each other in one cupped hand while a phone stopwatch ran beside the hand on the desk. The stopwatch starts from zero on camera, and RecordSetter tracked every swap on the unedited video, one rotation each time the two batteries trade places, at about one a second for the full minute, which fits Yanhao's count of 62. D batteries are far bigger and heavier than the AA cells in Yanhao's other rotation records, and neither one leaves the hand.

Yanhao Deng of Chenzhou, Hunan, rolled two D batteries around each other in one cupped hand for thirty seconds, with a phone stopwatch running on the desk beside the hand. The stopwatch starts from zero on camera, and RecordSetter checked the unedited video frame by frame: the batteries trade places about once a second until the stopwatch passes 30 seconds, which fits Yanhao's count of 30. Thirty seconds is a short window for batteries this size, and neither one leaves the hand.

Yanhao Deng of Chenzhou, Hunan, rolled two D batteries around each other in one cupped hand for ten seconds, with a phone stopwatch running on the desk beside the hand. The stopwatch starts from zero on camera, and RecordSetter went through the unedited video frame by frame: the batteries trade places 11 times before the stopwatch reaches 10 seconds, matching Yanhao's count. Ten seconds leaves no room for a fumble with batteries this big, and neither one leaves the hand.
