Calculator Prediction

Calculator Prediction is a mentalism and close-up magic trick where the magician asks a spectator to perform a series of mathematical calculations on a calculator, leading them to a final number. The magician then reveals a prediction that matches this number exactly, creating a moment of astonishment as it seems impossible for the magician to have known the outcome in advance. This trick is ideal for impromptu performances and requires no pre-show setup, making it versatile for various settings. Buyers should note that it involves simple mathematical principles and can be performed with any standard calculator.

Effect

The Calculator Prediction trick presents a clear mentalism effect for audiences. A spectator uses a calculator to perform a series of mathematical operations with a number they freely choose. The magician reveals a final prediction that matches the spectator's calculated result exactly. The outcome appears to be a genuine mathematical coincidence that the magician could not have controlled or known in advance.

Full details

This trick is a mathematical-based prediction effect. It uses a standard calculator, which can be borrowed from an audience member. The method relies on a specific sequence of operations that always produces a predictable result, regardless of the initial number the spectator selects. The magician prepares a prediction before the trick begins. The spectator's actions with the calculator lead them to the number the magician has already written down. The method is self-working and does not require sleight of hand or advanced mathematical knowledge from the performer.

Who should consider the trick

Magicians who perform mentalism or close-up magic should consider the Calculator Prediction. It is suitable for performers who want a strong, self-working trick that uses everyday objects. It works well for walk-around situations or impromptu performances where a calculator is available. This trick is also good for magicians who prefer effects with a logical or mathematical presentation over pure sleight of hand.

Information on how difficult it is to perform

The Calculator Prediction is not difficult to perform. The method is straightforward and can be learned quickly. There are no complex moves or sleights to master. The main challenge is presenting the sequence of instructions to the spectator clearly and confidently. A performer must be able to guide the spectator through the mathematical steps without revealing the secret principle. With minimal practice, most magicians can perform this trick effectively.
