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!!

Saturday Sail on #gecko40 . Easy 6kts in 10kts of wind. ▫️ We can't go far with the lock down restrictions, just out and back, and it's tempting to keep going to Mallorca 😉. ▫️ Anyway, all good as it's working. The numbers are coming down and we are allowed to move around Catalunya from tomorrow, so we are planning a trip to the Ebro Delta. ▫️ Head to 'kats.co/gecko' for more info on Gecko and 'kats.co/n40' for our owner's review. Have a good one! ▫️ #multihulls #catamaransailing #sailing #catamarans

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
