Spinning a Skateboard Wheel at 100,000 RPM

At a speed of 30 MPH, a skateboard wheel spins at about 5000 RPM. The guys at the Waterjet Channel wanted to see how quickly they could get a wheel to spin under the pressure of their 60,000 PSI waterjet. After realizing that ordinary plastic wheels wouldn’t hold up, they milled their own out of aluminum.
