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!!

Guido Broggi, boat captain di Maserati Multi 70, spiega il danno subito al pistone del foil alla partenza della Cape2Rio 2020 e la soluzione trovata dal Team italiano. Alle 12 UTC Maserati Multi 70 naviga con 37 miglia di vantaggio rispetto al suo concorrente LoveWater. Il vento è in calo, tranne qualche groppo, e il trimarano italiano naviga tra i 20 e i 30 nodi di velocità. #Cape2Rio2020 #MaseratiMulti70 Tracking: https://yb.tl/c2r2020 Sito web: https://maserati.soldini.it/ Facebook: https://www.facebook.com/giovannisoldini/ Instagram: https://www.instagram.com/giovanni_soldini/ Twitter: https://www.twitter.com/giovannisoldini/
