The Twister dares you to push the boundaries of freestyle windsurfing, inspiring you to expand your skills and master new moves and combinations. With its high-entry rocker and a narrow rear foot section, the Twister maximizes acceleration and top speed, delivering incredible pop for higher and more radical rotations. While the exceptional pop gives you the airtime needed for the latest power moves, the compact outline facilitates quicker and more controlled rotations. Jump aboard the Twister, push your own limits and redefine the boundaries of gravity! Find out more on https://tabou-boards.com

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!!
