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!!

La notte è turbolenta. Alle 4 giro come un grillo a controllare oblò, ormeggio, previsioni, etc. Alle 6:30 circa ci svegliamo per spostare l’ormeggio in un’altra baia, così andiamo a Cala Major, vicino a Palma, per lavorare indisturbati. Restiamo al pc fino alle 18:30, orario in cui chiudiamo tutto, tiriamo giù il gommone e il fuoribordo, e andiamo a fare due passi. Tappa supermercato: rimpolpiamo il frigo in vista della traversata sulla Sardegna. Stasera il programma è chiaro: cena presto e a letto presto che domani la sveglia suonerà (troppo) presto 🥲 Destinazione: Carloforte 🐟
