No you’re not hallucinating, what you’re looking at is the worlds first amphibian personal sports vehicle. The vehicle is called “Quadski” which is a mix between a jet ski and a land quad.  With a push of a button the wheels rotate upwards turning your four-wheeler into a fully functional jet ski.  The Quadski is capable of traveling 50 mph on both land and water. Although it’s meant for recreational use, the Quadski could also be used by the military, or for rescue missions.
