Beihu-Chenzhou-Hunan, SAR, China / October 12, 2026

Yanhao Deng spun two AA batteries around each other inside one cupped hand in Chenzhou, Hunan, with a smartwatch stopwatch propped beside the hand. The stopwatch is started on camera and keeps running for about three seconds while the batteries turn, and the quick thumb-driven rhythm, about three rotations a second, fits Yanhao's count of 3 for the first second. Blink and you miss it.
