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!!

Hey humans, it’s me, Nala 🐾 After all that travelling, it was finally time to stretch our legs in the Azores. Of course, my humans came too. Someone has to carry the treats 😹 The Azores are full of new smells, green hills, and interesting things to inspect. I think Simba enjoyed the walk too… although he mostly pretended he was only there to supervise. 🇵🇹🐾❤️ #catsonacatamaran #azores #catwalk #adventurecat #travelcat #boatcats #catlife #azoresislands #PetAdventure #happycats #outdoorcats #travelwithcats #catlife #cattravel #exploremore

In this inspiring episode of the Salty Podcast #40, I chat with sailor Kirsten Neuschäfer, the remarkable winner of the 2022 Golden Globe Race. This grueling, solo, non-stop race around the world challenges sailors to navigate without modern technology—no chartplotters, GPS, or satellite weather forecasting—and all without assistance - on a 36' sailboat! https://tinyurl.com/SaltyPodcastPlaylist #SaltyAbandon #Sailing #SaltyPodcast #GoldenGlobeRace #SoloSailing #OceanAdventure
