⛵ En pleine traversée de l’Atlantique Sud, Naomi James a un jour failli perdre son mât… à cause d’un nœud mal serré ! 🌬️ Une rafale brutale a fait lâcher une drisse vitale, et la voile est tombée comme un linge mouillé. Pendant que le bateau roulait dangereusement, elle a dû grimper seule dans le gréement, en pleine mer agitée, pour sécuriser ce qui restait. ⚓ Elle a réussi, à bout de forces, à improviser un système de fortune pour continuer… prouvant qu’elle n’avait pas seulement du cran, mais aussi un sacré génie marin. #NaomiJames #femmesfortes #Voile #Aventure #nautique #navigation #JoyEnMer

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!!
