Digital Deception with DVD by Marc Oberon (3285)

You remove a key and ring from your
pocket and explain that your audience will create a three digit number.
You ask several people to name a single digit number and these are put
together to create a random three digit number.

Amazingly, the number named exactly matches the number digitally printed on the key ring!

Includes: Instructional DVD, notepad, permanent marker, key and tag gimmick, and detailed instruction booklet.
