Compact Key by Marvoyan

More than magic, this is an ice-breaker that can be performed on a whim.

Compact Key is a twenty-second routine designed for any impromptu situation. Pretend to show a new security device, A Compact key. Removed the head of the key from its stem separating the key into two pieces. The pieces are instantly restored into the original key. This is repeated several times until the spectator smiles and realizes that he has just seen something impossible.

The key can be examined before and after the routine. Do it at a moment's notice. Comes complete with all necessary props and photo-illustrated instructions.
