Description
Or you can put a blank piece of paper in the glass with a pencil, put a napkin over it and let a spectator draw a card. When you remove the napkin and pick up the note and give it to the spectator, he unfolds it and the pencil has written which card he drew.
The only limit to what this glass can be used for is your imagination.
Mini: 4.7 cm in height and 4.5 cm in diameter.
