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!!

Check it our for yourself! - https://amzn.to/4iNrN2g When Trent first suggested getting a Milwaukee Stick Transfer Pump for the boat, I honestly thought it was a waste of money. But I’m happy to admit I was completely wrong. We've had massive rainstorms here in St Martin — over 100 gallons of rainwater ended up in our dinghy in just one day. Normally, it would have taken 20+ minutes (and a lot of effort) to bail it out by hand, but with the transfer pump it was emptied in about 3 minutes, no heavy lifting, no drama. The pump runs on the same Milwaukee M12 batteries we already use with our other tools and can be used in other areas of the boat, like the water tanks, bilges and lockers. In our opinion it's definitely one of those tools that saves time, saves effort, and just makes boat life easier. #MilwaukeeTools #BoatLife #ToolReview #LiveaboardLife #SailingGear #DIYBoatProjects Prefer to support the channel as a 1-off?
