A few months back I asked for your suggestions of what to put in front of my Schlieren setup. I have now tried a few, even lighting a ping-pong ball on fire. I adjusted the setup so it is now a color schlieren (although in a budget sort of way because I used cellophane). I am still keen to image the Leidenfrost effect in Schlieren so I will do my best to make that happen.

In the first part of this video I try to answer a lot of the questions I received after posting the first video. I also show that the setup can be used to project Schlieren images on a screen or wall surface.

Wow! This is very well done. Excellent results! Remembering when I was a kid, reading about Schlieren imaging in an encyclopedia, and 1960s science books my dad brought home. Illustrations, diagrams in books just don't convey enough. Long live Youtube!

How about re-igniting an extinguish candle by putting a flame in the smoke coming off it?
