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!!

💫 Catherine Chabaud, première femme française à avoir bouclé un tour du monde à la voile en solitaire, sans escale et en course, lors du Vendée Globe 1996-1997. ⛈️ Lors de ce fameux Vendée Globe, alors qu’elle affronte les mers du Sud seule à bord de son monocoque “Whirlpool-Europe 2”, elle traverse une tempête d’une violence inouïe. Les vagues sont si hautes qu’elle ne voit plus l’horizon. Elle raconte qu’à un moment, elle s’est surprise à parler à haute voix à son bateau comme à une personne : 🐋 « Je lui disais : Tiens bon, mon grand. Allez, on y va tous les deux, on sort de là ensemble. » 👍🏽 Ce moment d’intimité entre la navigatrice et son voilier illustre magnifiquement la relation fusionnelle que peuvent entretenir les marins avec leur embarcation, surtout dans les situations extrêmes. Elle expliquera plus tard qu’elle n’a jamais vraiment eu peur à ce moment-là, parce qu’elle avait confiance en son bateau, et que c’est cette confiance réciproque qui l’a portée jusqu’au bout. #Voile #VendéeGlobe #CatherineChabaud #aventureenmer #navigation #femmesfortes #JoyEnMer
