What would happen if all 1.3 billion Chinese jumped in unison?

What would happen if all 1.3 billion Chinese jumped in unison?

Umm...nothing, really.
That's the deduction from an experiment carried out today with tens of thousands of human lab rats who attended the German music festival Rock at the Ring. The idea of enlisting rock-crazed youths to advance geological science got started when the creators of a science program on German television asked themselves what would happen if the entire Chinese population engaged in synchronized hopping.
They saw Rock at the Ring as an opportunity to provide an answer to that question on a microcosmic scale. At the concert, the band We Are Heroes cued the thousands of rock fan/hoppers (total attendance 50,000) with drumbeats to go airborne, while the program's crew recorded the event on videotape and the Potsdam Geological Research Center recorded it on seismometers.
A producer of the science program, Quarks & Co., characterized the "gang boing" as a "mini-mini earthquake," according to a news report from Deutsche Welle." A seismometer measured four oscillations per second, while the earth moved only one-twentieth of a millimeter. "We showed that people cannot start a (real) earthquake by hopping," remarks Ulrich Gruenwald, producer of the program, who emphasized the difficulty of getting tens of thousands of people to synchronize their jumps.
Maybe just stick to the Wave.
