You explain to the audience that you will teach them a magic trick.
You drop the Jumbo card between the two boards on the tray. Reverse the tray so that everybody can SEE that the card is resting in the ribbon loops under the tray. Explain that magicians fool the audience this way.
Show the trick again, only this time the card actually disappears!
This version is hard to find in this design.
