El Duco’s Add a Number Pad PLUS

Add a number is a classic mental effect. three spectators write down three different numbers. These are added up by a fourth spectator and the total matches your prediction. The El Duco’s Add a Number Pad is considered by many professional mentalists, to be the best version of this effect. This is the PLUS version of the classical El Duco Add-a-Number Pad! You can still do all the things you can do with the standard Add-a-Number Pad and we have added the features of a Locking Himber Wallet by adding a corner pocket to the writing pad (of course on both sides). Thanks to this feature you will have both a forcing and a switching device.

We have created a NOTE BOOK in finest calf leather. Inside is a pad of Post It papers (3 x 5 inches). At the opening side of the note book there is a holder for a pen. When a pen is in place it also locks the note book.
Now to the handling: Ask three spectators to write any number between 1 and 1000. When the last spectator is ready, he puts the pen in place and throws the book to any person in the audience. He or she opens the note book and makes the addition. IT MATCHES YOUR PREDICTION!!

What really happens is that the note book has built in magnets that automatically switch the side of the Post It pad when the last person opens the book. It is safe and easy to do. thanks to the locking pen there is no risk the note book will open when they throw it. And remember you never touch the note book after the third person has written his number!
