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.

Supersonic air jets into water

I wanted to see what it would be like to shoot an air jet into water. This first video is a converging nozzle and will have sonic flow at the exit.

This video is a converging/diverging nozzle and will have supersonic flow at the exit.

This is a converging/diverging nozzle into a little bucket.
