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!!

Ahoy! Sailing bliss or disaster? We're leaving the Eagle Point marinara a raw sail downwind to our marina in Lake Dallas. Cyndi and I have come this far to try our hand at a downwind wing-on-wing sail plan, after an easterly beam reach, then a westwardly sail. We had a great time practicing the training run and the down-wind sail setup. We leave our old friend, Sneaky Pete's Grill, and Eagle Point Marina behind and press forward, sailing back to Lake Dallas in our Catalina C-30 Tall Rig sailboat named Zanadu! Cheers! - Rodney & Cyndi #sailingcouple #sailingintonirvana #boatlife #sailinglife #sailingcouple
