Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

☠️ More: https://youtu.be/ERZZe8F01MY While sailing the Bahamas on a broken sailboat we found something dangerously amazing: Thunderball Grotto near Staniel Cay in the Bahamas is amazing. It's a cavern you can only enter by jumping through a very high hole in the roof or by swimming through a cave. So it ain't for wusses. 2 James Bond movies have been filmed here, including Thunderball. I did a kill count for the scene filmed underwater here, and I think it was 19? Maybe you can fact check me. https://youtube.com/shorts/VLqBCstRmXI #sailing #bahamas #jamesbond 19 Men Killed Here 💀 Thunderball Grotto
