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!!

Much like the LMF 33 LC, the 28′ Landing Craft was built for commercial purposes. The Aluminum hull and drop down bow door, allow for easy beaching on less than desirable coastlines. The 28′ was built for the Anderson County fire department in South Carolina, so this boat had a built in water tank and pump so a hose can be connected for fire fighting operations. Being a custom boatbuilder, Lyman-Morse will be able to customize future orders to fit the exact needs of the buyers. Whether you are looking for a more commercial use boat or something simple to get your equipment out to your private island, the LMF 28 LC is the boat that can do it all. This vessel was equipped with twin Yamaha 250’s which allows for cruise speeds in the mid 30’s and 46+ knots WOT. #boatbuilding #maine #aluminumboats

BELLA UNO is the perfect fast, light weight, cruiser/racer. Designed by Perry/Andrews in 1998. She is an ultralight-displacement-boat (ULDB) with all the performance and creature comforts on board. The current owner purchased BELLA UNO in 2013 and commissioned a complete no expense spared, top-to-bottom refit, which was completed in 2015.
