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!!

POSITIONING YOUR YACHT Watch as Nick, sets the yacht up in position with lazy lines. =========================== Watch the full training video here - https://youtu.be/-OPs960oR88 =========================== Transcript Always have your boat hook ready and logged off in full extension. Voila And if you've got another person here or you know this might be people that are learning to dock on their own as such or with their crew it's really good to give that person the um other other hook just to put down. Now just have a look here see I've come up with a cross lazy line don't worry about this okay. Just grab the other side and keep going. If you get worried about your lines which one they're giving you, you lose the time and the boat will swing away. See why I took my jacket off. Okay so this will pull my bow over a bit. Again I'm not going to worry hugely about getting these super tight I'm just going to get them on and secure and I'll set the position of the boat later. =========================== Looking to sail in Croatia?
