Euler’s Disk is an interesting toy which allows you to get a real feel for a physical singularity.  If there was no friction, slipping, energy loss or air to complicate things- then the equations predict in a finite length of time it should spin infinitely fast. Of course this isn’t possible, and there are several explanations for what stops the disk from spinning quite abruptly at the end. [more]
