How Fast Is a Vacuum Cannon? Is It Really Supersonic? Measuring the Speed Of My Vacuum Cannon

In this video I do another test with my vacuum cannon to test if it is really supersonic. The vacuum cannon works by accelerating a ping pong ball at potentially supersonic speeds do to the vacuum created in the PVC pipe. However, I haven't measure the actual speed, so I thought I would give it a try.
