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!!
Hey everyone, due to the craziness of prepping for crossing the Panama Canal and because I did not meet anyone that could deliver data to Germany, the upcoming episodes have been delayed a little. The new material is on its way now, and I hope we can be back on track soon. Sorry if anyone was worried. i thought u had seen my update about crossing the canal and knew that all was good. Ahoy, Nike & Karl
