Similar to the popular CRAZY CUBE trick, but made with a distinctive blue barrel container!
Your spectator secretly chooses the number on one side of a die, then seals a die into a small blue container, then seals that container into a second container. Instantly, you can tell the spectator which number he chose! Best of all, this trick can be repeated immediately, and you will be correct every time!
WARNING: CHOKING HAZARD. Do not put the dice in your mouth. Not suitable for children under 5 years of age.
And that's all you need!
