Magical Super Site (by Magic Makers Inc.)

Display the five different colored brass discs and
the brass container. While your back is turned, a spectator selects and places one disc in his or her pocket sealing the rest in the container. Instruct the spectator to screw the top on all the way and place it on the table. Without being able to see in their pocket or in the container, you instantly and correctly name the color disk in their pocket!
