The Children's Giant Jump was a

Premise
Organizers of Science Year from The Association for Science Education instructed schools across the United Kingdom to direct their students to simultaneously jump for 60 seconds at 11 a.m. Students made measurements at their schools, while scientists also tried to pick up the tremors using the United Kingdom's seismic sensors.

Outcome
Though it was calculated that the event would release the same amount of energy as a Richter magnitude three earthquake, since it was spread out over the entire country, the effect was barely noticeable on seismic sensors, and it was impossible to distinguish the effects of this event from the many micro-quakes that hit the United Kingdom.
