Code Number: 8B40.30
Demo Title: Membrane Table
Condition: Excellent
Principle: Membrane Table
Area of Study: Astronomy
Equipment:
Basket with rubber membrane, Hula Hoop with Spandex membrane.
Procedure:
NOTE: The apparatus used for the fabric membrane sheet is located in the 5B10.70 "Potential Field Model" box.
Place the camera looking straight down at the top of the basket. Place the larger and heavier balls very gently into the basket. Replacement of the membrane is necessary when it shows undue wear. Do not leave anything on the membrane during storage as stretching may occur.
