  1. Cohesion force.

    The spray bottle was empty enough to be classified as garbage, so was attracted to the rest of the crap on the ground. šŸ˜Ž

  3. As I see it it has to do with all of the following: friction, gravity, periodic motion, dampening, center of mass, misalignment of contact points and rotational axes, resonance, positive feedback, and inverted pendulum.

    Please don’t ask me to put all that in some sort of sensible order. šŸ™‚
