Coral reefs may cover less than 1% of the ocean, but they support nearly 25% of all marine life, making them one of the most vital ecosystems on the planet. Protecting them isn’t just about saving beauty beneath the surface… It’s about safeguarding the future of our ocean. At SeaTrek, coral conservation is more than a cause, it’s part of the adventure. Guests who join our sailing journeys don’t just explore the reefs, they help restore them. Through hands-on coral planting and guided conservation activities, every trip becomes a chance to connect, to learn, and to protect. They can’t cry for help, but you can speak, share, and act. 🌺 Be part of the mission. 🌊 Sail with purpose.#SailingForGood 🐠 Help coral thrive again. #CoralConservation #WorldOceanDay #EcoAdventure #SailWithPurpose #ProtectOurOceans #OceanLovers #SustainableTravel #MarineLifeMatters #EcoTravelEurope #BluePlanetLove #WildlifeConservation #AdventureWithImpact #NatureFirstTravel #TravelForThePlanet

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!!
