2 - Jumpy hoop

Given enough angular momentum, a hoop with a mass attached to it may demonstrate a jumping motion when it is rolling. Explain the phenomenon and how it depends on the relevant parameters. Is it possible to reproduce this behavior with any unbalanced mass distribution on a wheel? What happens when one changes the profile of the ground? Can you add a mechanical contraption (that will not touch the ground) to the hoop to increase the maximal height of the jump? https://youtu.be/ETRpkp03stQ
