One of our favorite Anverdi effects.  You can have fun with this one.

 

The bell is examined and then placed on the stand.  A swinging hammer mounted to a clear upright is shown and also placed on the stand.  The clear upright shows there is no connection to the base, electrical or mechanical.

 

At your will the hammer swings and rings the bell.  The spectator can even take the hammer and bell off and replace them and yet the bell can still be rung at your will.

 

Condition: Very good, tested and operational.
