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!!

Passengers onboard our Silversonic dive and snorkel vessel and Pro Dive Cairns Liveaboard vessel had rare whale shark encounters within days of each other at Turtle Bay on the Agincourt reefs (Silversonic) and at Flynn Reef off Cairns (Pro Dive Cairns). The spectacular whale shark sighting encountered by Silversonic's passengers and crew measured around 6m in length and was travelling slowly in a north west direction. Video footage thanks to Shane "Sharky" Down! Snorkelling with the whale shark photos thanks to Pro Dive Cairns. http://www.silverseries.com.au/ http://www.prodivecairns.com/

Em dias de vento, o veleiro torna-se palco de uma dança emocionante entre as velas e as ondas. O rugir do vento se mistura ao som das águas agitadas, criando uma sinfonia única. A bordo, cada rajada é um convite à adrenalina, enquanto o barco corta as ondas com elegância. Dias assim são inesquecíveis, marcados pela intensidade do vento e pela liberdade que só o mar revolto pode proporcionar. ⛵️🌬️ #Veleiro #VentosMarítimos #AventuraNoOceano
