In this video, the puck sits on a room-temperature aluminum ramp. Warmed by the ramp, the dry ice sublimates off the bottom of the puck and forms a thin layer of CO2 gas that levitates the puck, allowing it to slide down the ramp with very low friction. This process also creates a cool and mysterious smoky appearance of the puck, perhaps contributing to Einstein's excitement. The puck eventually compresses a spring and bounces back up the ramp—with clearly bewildered Einstein looking on. While energy conservation is at the heart of this analysis, you will have to use many different concepts and ideas to get all the answers. Don't disappoint Professor Einstein! Note that the screen has a superimposed frame counter, a linear scale, and a protractor scale—all of them will be important in your analyses!
