First attempts at Schlieren

I just got my spherical mirror. Here is one of my first attempts at Schlieren. This is imaging the heat that is coming from a candle.

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.
