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!!

En un día soleado, me pongo al timón de mi barco BritisTiger, desde la proa, navego como un jinete cabalga a lomos de su corcel. Con el viento en mi ayuda, dejo que las olas me guíen hacia la libertad del mar. 🌊⚓ ¡Acompáñame en esta travesía y siente la emoción de la navegación a vela! ¿Te gustaría navegar como yo?

Plankton doesn’t have a chance to get away from those Mackerel's mouth traps! The main food source for Indian #mackerels is plankton. These schools of fish swim with their mouths open as they feed through areas rich in plankton. Their main food sources are phytoplankton and microscopic zooplankton, such as ostracods, diatoms, and polychaetes in their larval stages. Have you ever encountered them on your dive before? Join us to discover the beauty and wonders of the #underwaterworld of #RajaAmpat.
