| Insert description of apparatus, its component, what it is demonstrating. | The large copper blade of the Guillotine is released from a height of 7 feet 10 inches. Strong Magnets are placed about a foot above the chopping block. These magnets are strong enough to slow the blade to almost a stop with induced Eddy Current within the copper blade.

Location: Floor Item Room 2237.
attachment:Guillotine-28-400.jpg
Description:
The large copper blade of the Guillotine is released from a height of 7 feet 10 inches. Strong Magnets are placed about a foot above the chopping block. These magnets are strong enough to slow the blade to almost a stop with induced Eddy Current within the copper blade.
The Guillotine with base is some 10' 4" tall, 15.5" wide, and 1.5" think. The base is 23" x 23" x 28".
