Snake Eyes by Tom Burgoon

I have recently bought this and I am very happy with this purchase. The description from the site didn't really describe the effect.

Basically, you show a pair of dice and roll them in your closed hands. You claim to be able to control the roll ever time...but you never let the spectator see if you're correct! Not worry, you ask them to get close and you'll show them the next one. Give the dice a shake and say "Snake Eyes" and from your closed hands comes a large rubber snake head!

The term snake eyes is the outcome of rolling the dice in a game of craps and getting only one pip on each die. The pair of pips resembles a pair of eyes, which is appended to the term 'snake' because of the long-standing association of this word with treachery and betrayal. Because this is the lowest possible roll, and will often be a loser in many dice games, the term has been employed in a more general usage as a reference to bad luck.

I have tried this on some people and the reaction varies from jumping up from their seats, screaming and some just smile and say "where can I buy this?"

A simple gag/ effect that is small enough to carry around. Fun to do but you must know who you do it to. Highly recommended.
