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!!

The Evinrude MFE (multi fuel engine) is one unusual outboard - it can run on everything from gasoline to Jack Daniels. It can be submerged, drained, and fired right up. And it's the choice of the Navy Seals, when it comes to outboard engines used for their landing craft. Want to learn more about the Evinrude MFE?
