8B40.20 - Black Hole Surface - Fiberglass or Plastic

Code Number:
Demo Title:
Black Hole Surface - Fiberglass or Plastic
Black Holes, Gravity Well
Area of Study:
Stellar Astronomy
Fiberglass and Plastic "Wishing Well" Cones.

Use 1 inch ball bearings for the large Fiberglass cones.  Cones of 24 inch diameter and 40 inch diameter are available.  There will appear to be an event horizon just before the ball drops out of the cone and into the holder.

Use 1/4 inch ball bearings for the smaller (10 inch diameter) plastic cone.
