Inside I placed a 2.188" diameter steel ball, taken from one of the largest ball bearings that Emerson uses. The ball also weighs ~1.5 lb. (Don't expect to get them cheap -- motors that use that size ball are rated for 4000 horsepower and stand about fifteen feet tall. Production quantities are small relative to most FRC components.) So the total weight is about 3 lb. and the center of gravity shifts about six inches when the ball rolls from one end to the other.

As you can easily imagine, the weighted capsule is unwieldy! Grab it in the middle, tilt it slightly, and it will torque your wrist. Holding it level is a challenge.

A diabolical gamepiece if ever there was one.
That would be cool i would have a magnate on the device picking it up so the steep ball wont move around =.
