Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
