“Ten Meter Tower” is a short film by Maximilien Van Aertryck and Axel Danielson. Through an online advertisement in Sweden, the filmmakers found 67 people who had never been on a 10-meter (about 33 feet) diving tower before, and had never jumped from that high.

They paid each of them the equivalent of about $30 to participate and filmed it all with six cameras and several microphones. The duo say it was important not to conceal the fact that this was an arranged situation, and thus chose to show the microphones within the frame.

Ultimately, about 70 percent of those who climbed did jump. They noticed that the presence of the camera as well as the social pressure (from those awaiting their turn beside the pool) pushed some of the participants to jump, which made their behavior even more interesting.
