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!!

There’s always an intriguing find on every dive, especially when you dive around the #reefs of the #CoralTriangle in #Komodo and #RajaAmpat. The coral reefs are home to many different animals, and they all live together in harmony. #Fish of all colors, shapes, and sizes swim around like living jewels. #Seaturtles move gracefully through the water, and octopuses hide by changing their appearance to match their surroundings. But there's more to it. Even the tiniest creatures, too small to see, are vital to this underwater ecosystem. Sponges, soft corals, and #anemones provide homes and food for many other animals, like #crabs and snails. Every time you go diving on a coral reef, you can discover something new. It reminds us how important it is to take care of these amazing places, so they can continue to astound us and be home to all these wonderful creatures for a long time. So, please don’t touch them as the corals can break easily and they take a very long time to grow back. Do you want to journey with us on an exciting adventure to some stunning dive sites and see the wonders that Raja Ampat & Komodo have to offer?
