Any guesses??? 
An extreme close up of a CAD image of an orbit ball
Guess again 
Is it a helix that brings balls up?
It’s the makings of a staircase up to your fairy princess’s room 
Maybe 
Thats a helix fo sho. The question is, does it bring the balls down or does it bring them up like an auger? I’m gonna guess bringing them down.
It doesn’t have to be an auger to move balls up. Motion is relative to the frame of reference.
giant gumball machine:rolleyes:
Looks like an Archimedes screw.
Helical ball hopper, similar to 233 in 2006 is my guess.
