At the far end of the 14 foot barrel, a gunpowder explosion is used to compress hydrogen gas to as much as 1 million times atmospheric pressure. The compressed gas gets released and sent down the launch tube, firing a projectile pellet at speeds between 7,000 and 15,000 mph. The shot enters the cylinder, in which low pressure or even a vacuum is maintained. High-speed cameras mounted on windows around the cylinder record the impact aftermath at up to 1 million frames per second.
