1R50.40 Ball Bearing Model
Single crystals, frustrated packing, grain boundaries, vacancies, vicinal surfaces
Ball bearings demonstrate single crystals, frustrated packing, grain boundaries, vacancies, vicinal surfaces and so on.
-  Ball bearing model
- The ball bearings can become electrostatically charged. If this happens, a few ball bearings will 'hover' near the surface
- This demonstration works best when the model is nearly flat on the table/overhead. It does not work when it is held upright
- To demonstrate a single crystal, slowly move the balls to the 120 degree end.
- To demonstrate frustrated packing, move the balls to round end.
- PIRA 1R50.40
- Don't attempt this at home!
- This demo was made from two lucite plates and about 4000 1/16" ball bearings
