The Moon Jump iPhone app
The idea is very simple and it’s basically a physical crowdsourced experience. Download the iPhone app (for free), you will get a message, the message will tell you when you should jump. Everyone who has got this app receives the same message, so let’s jump all together at the same time.
If you jump at the exact time while holding your iPhone, the device can calculate how high everyone jumps at the same time. When total distance of jump reaches to the distance from the earth to moon, the brand behind the app (still unknown) will give you a special gift.
