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!!

Practicing the use of radar provide you with an edge when you really need it. We sailed from Sandoy to Hestur (the faroe islands) and the fog prevented us to see the islands. When we were arriving at Hestur, the radar and navionics help us identify the ferry which was heading to Hestur as well, so, we made a U turn to give the ferry priority to head in first. Then, the tide was running fast, so Skipper Chris did the ferry gliding to let us have a smooth and safe entrance.
