Story summary
- U.S. organizers of World Clap Day asked an estimated 8.3 billion people to clap for one second at 10 a.m. Eastern on August 16, 2026.
- Oxford professor Robin Cleveland calculated each clap releases 8 millijoules, yielding about 65 megajoules worldwide—enough to boil roughly 25 liters of water.
- He said the total equals a few sticks of dynamite and will not cause a measurable atmospheric pressure spike.
