Thumb Tip Bill Change
Transforming a Bill
The routine begins with a piece of paper on which a spectator writes the value of a bill. After an initial production, the money obtained does not match what they asked for: the second phase transforms that bill into one of a higher value. Borja Montón performs the complete sequence and then explains its two parts separately.
The core of the lesson is the thumb tip change. It covers bill preparation, the folds, and hand coordination to display it on both sides and unfold it smoothly. The explanation alternates between the magician's POV, slow-motion repetitions, and full-speed performance runs. The instructor emphasizes not rushing the unfold: the clarity of the transformation depends on making the movements look like a continuous action.
Managing Props and Attention
It details how to distribute the props in your pockets and how to tie their retrieval into natural gestures that the audience understands. A jacket makes this organization easier, although different pocket options are also discussed. Eye contact, actions in transit, and the moment of relaxation after a surprise are also worked on.
The lesson compares two different moments to prepare for the transformation and studies how to display the final bill, hand it out, or put it away without interrupting the performance. Humor and patter are provided as examples that can be adapted to your persona.
Props and Optional Opening
To practice the main change, you need two bills of different values or appearances and a sufficiently sized thumb tip. The folding technique is taught right in the lesson; you don't need to know a prior transformation.
The complete routine adds writing paper, a marker, commercial flash paper, and a lighting device. The lesson dedicates a section to this material and its flammability. That opening is optional: you can study and perform the bill change without fire.
Rehearse the folds first and then the sequence with the pockets and the patter, aiming for a uniform movement before performing.
