Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Edited from to 1/4th 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!!

we sailed with over 20 knots into a huge wave and even if were flying our smallest and strongest kite, blew up. We are currently saving our two larger but thinner kites not to loose one more similarly as the sea state continues to be rough and we will need them in the long race. We are currently VMG running with our fractional zero that might not be optimal and result temporarily in reduced boat speed. This is normal in a race like this, and our fighting spirit has just gone up. We're looking forward to reaching half way!"
