- Ideas for creating a low friction horizontal rotating platform for rotation experiments.
I am looking for a rotation devise like that one in this video below (from 00:40 seconds). Does anyone know where to get one, or have any idea about how to create a nice and stable rotation setup for experiments without too much hassle and DIY? A bike wheel won't do, a disk is better, because I need to know the moment of inertia from the shape of the freely rotating platform.
