Very Cool.

That was amazingly interesting! I had no idea how we define a kilo

That looks amazing! Can I put MY balls on it?

Is he moving the sphere or is the sphere moving him?

You mean the massaging thing that grinded the ball down to a smaller size...? Sure!

Yes! That is exactly what I mean! Meaning of course that my balls are too big and need to be smaller. "Laughs out Loud"
