Kurze Hose Erstellen

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!!

Merry Christmas ~ Sailing Free Spirit We are going to take a little break from posting videos for the next few weeks but we will be back soon without our continued adventures as stops as we made it to our final destination for this year. See you again after the holidays! Much love from Free Spirit and Crew (aka, the puppies).

Full Send Friday, but for real. The Polish team of Mikołaj Staniulewicz and Jakub Sidorek — North-powered, totally in the flow. The 49er flies, the water explodes, focus at its limit. When you're not just going fast — you're living at speed. @northsails #FullSendFriday #SailingFast #HighSpeed #SailingLife #AdrenalineOnWater #spinnakermagazine #spinnakerbureau
