Here is the acrylic tank that I built in action. I shoot an air jet from my air compressor into the tank.

Side view of air jet from converging nozzle into a bucket of water

This is the same as the jet from the converging nozzle but is viewed from the side. I cut out part of the bucket and replaced it with polycarbonate. It is played back in full in real time and then 32 times slower for the first part of the video.
