Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) 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!!

To be lauch at the Düsseldorf Boat Show 2016. This new member of the Lagoon family has style and a strong personality. While keeping a family resemblance and retaining the main features of the latest generation of Lagoons, it shows us a new path: unhurried evolution, a new "organic" approach, in search of harmony between living space and man. An elegant silhouette, flowing curves which, by virtue of a noticeable acceleration of the lines in the bows and in the new coachroof design, emphasise the powerful and dynamic nature of this new model… A VPLP design naturally, a guarantee of performance under sail! Lanzamiento en el Salón Náutico de Düsseldorf 2016 Este nuevo miembro de la familia Lagoon tiene estilo y una fuerte personalidad. Todo manteniendo un aire familiar y conservando las características principales de la última generación de Lagoon, nos muestra una nueva vía: una evolución totalmente suave, un nuevo enfoque «orgánico», en busca de la armonía entre el espacio vital y el hombre. Una silueta elegante, de curvas fluidas que, gracias a una aceleración de las líneas perceptible en los estraves y en el nuevo diseño de la caseta, destacan el carácter potente y dinámico de este nuevo modelo... Un plano VPLP: ¡garantía de rendimiento a vela!
