Learn what the Numerator Video trick is, how it works as a self-working mentalism technique, and a step-by-step guide to using it in your performances.
Quick answer
The Numerator Video is a self-working mentalism trick that allows you to reveal a spectator's chosen number without touching their phone or using any sneaky moves. This guide explains the method and how to perform it.
Understanding the Numerator Video Method
The Numerator Video is a revival of a classic method, originally featured as 'Old But Gold' in How to Read Minds 2. It is self-working, meaning the trick does the heavy lifting for you. You never have to touch the spectator's phone or do anything that feels suspicious.
Because it is self-working, the main challenge is presentation: you need to structure the routine so the reveal feels natural and surprising. The method itself is reliable, but your delivery determines whether the audience perceives it as genuine mentalism.
Step-by-step guide to using the Numerator Video
- Prepare your phone: Open the Numerator Video on your phone and have it ready to play. Make sure the volume is off or low so the spectator does not hear any audio cues. Common mistake: leaving the video visible on your home screen. Keep it open and paused so the spectator does not see the setup.
- Ask the spectator to think of a number: Hand the phone to the spectator and ask them to think of any number between 1 and 10 (or a range you have preset). Do not rush this step; let them choose freely. Checkpoint: ensure the spectator understands they are choosing a number, not a card or symbol. This avoids confusion later.
- Play the video and let it work: Ask the spectator to press play on the video. The self-working method will reveal their chosen number without any further action from you. Do not touch the phone or give any verbal hints. Common mistake: trying to guide the spectator's attention during the video. Trust the method and stay quiet.
- Reveal the number naturally: When the video ends, the number will be displayed or implied. React as if you have just read their mind. Keep the moment simple—do not overexplain or repeat the method. Checkpoint: practice the reaction in front of a mirror. A calm, surprised expression is more convincing than a forced 'wow'.
