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!!

I love powercats, so I was shocked to find one I hadn't examined yet at this year's Fort Lauderdale Boat Show. Climb aboard, for a First Look Video. We'll get a look-see at how this boat's laid out, but most importantly, how Arrowcat takes advantage of a cat's unusual foot-print. Inside the cabin, this builder manages to utilize every inch of use-able space - and then some. Check it out. http://features.boats.com/boat-content/2013/12/arrowcat-32-first-look-video/ For more boat videos, visit www.boats.com.
