Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. 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!!

A few days ago, Boris Herrmann sailing on Malizia - Seaexplorer passed the Scottish kelp forests that are being protected by Talisker and Parley. For every bottle of #Talisker “Made by the Sea" whisky sold, they donate 3€ to protect these areas. So cheers from the Ocean to the Ocean! #talisker #Taliskerxparley #OnefortheSea #paidpartnership Please drink responsibly.
