Pi Revelations by David Penn

Effect

Pi Revelations creates a moment of mathematical impossibility for the audience. A spectator freely names any four digit number, such as a PIN or a year. The magician then opens a book containing the digits of pi and immediately locates that exact number within its pages. The effect is a direct and clean revelation that appears to defy probability, blending mentalism with the intrigue of mathematics.

Full details

Pi Revelations is a product designed by David Penn. It includes a physical book printed with the first 50,000 digits of pi. The system uses a web based indexing tool to help the performer quickly find any number within the book. Internet access is recommended for the indexing system to function at its best. The product comes in two sizes: a larger A5 version for stage or parlor use, and a smaller A6 pocket size for close up performances. The method does not require any sleight of hand or advanced mathematical knowledge. The performer only needs to learn how to use the indexing system effectively.

Who should consider the trick

This trick suits mentalists and magicians who perform prediction or revelation effects. It is ideal for performers who want a clean and direct method that does not rely on traditional props like envelopes or boxes. Those who enjoy mathematical themes or want to add a intellectual feel to their act will find it particularly appealing. It works well in both close up and stage settings, depending on the book size chosen.

Information on how difficult it is to perform

The method is not technically difficult. It requires no sleight of hand. The main challenge is learning to use the web based index quickly and confidently. Performance difficulty is low, but practice is needed to ensure smooth handling of the book and natural presentation. Fiddlin' Johnny notes that the system works best with internet access, which performers should consider for reliability. The tutorial provided focuses mainly on iOS devices, so Android users may need to adapt.
