Step 1
Apply the Tape
Place a tiny piece of clear tape near the pad of your thumb. Keep it flat and discreet so it cannot be seen from the audience's normal viewing angle.
The Effect
The magician appears to write a prediction on a notepad and keeps the writing hidden. A spectator is asked to name a number between one and one hundred or choose a simple shape such as a circle, square or triangle.
When the notepad is turned around, the written prediction perfectly matches the spectator's choice.
🎭 Presentation Note
Present this as a theatrical prediction or mind-reading demonstration. The mystery comes from performance, timing and concealment—not a claim of genuine supernatural ability.
What You'll Need
- A small notepad with reasonably firm paper.
- A pencil for the apparent prediction.
- A tiny piece of graphite from a soft pencil lead.
- A very small piece of clear adhesive tape.
Use only a blunt, tiny piece of graphite. Avoid sharp fragments, and remove the gimmick immediately after performing.
Prepare the Secret Writer
Step 2
Attach the Graphite
Secure a very small, blunt piece of pencil lead to the tape. Only enough graphite to make a short mark is required.
Step 3
Check the Writing Position
Hold the notepad so your thumb naturally rests against the hidden writing surface. Rehearse making short, legible marks without changing your grip.
How to Perform the Trick
- Introduce the prediction. Explain that you will commit to an answer before asking the spectator a question.
- Mime the writing. Look down at the notepad and make a brief writing motion with the pencil, but do not actually write the prediction.
- Hide the page. Turn the face of the notepad away from the spectator while keeping your thumb against the paper.
- Ask for a choice. Invite the spectator to name a number or a simple shape. Keep the range manageable so the final writing can be completed quickly.
- Secretly write the answer. As you react to the choice, use the concealed graphite to make the prediction with your thumb. Keep the movement small and natural.
- Pause before revealing. Hold the moment for a second, then turn the notepad around and show the matching prediction.
Make the Secret Writing Convincing
✍️ Keep It Simple
Single digits and basic shapes are fastest to write and easiest to recognise.
👀 Control Attention
Look at the spectator while secretly writing. People naturally follow your gaze.
⏳ Use a Natural Pause
React to the named choice before revealing the pad. This disguises the brief writing delay.
📐 Protect the Angle
Keep the writing surface turned inward until the prediction is complete.
Suggested Presentation
“People often think their choices are completely random. Before I ask you anything, I'll write down the impression that comes to mind.”
Mime writing, turn the pad away and continue:
“Think of one simple shape—nothing complicated. Fix it clearly in your imagination, then say it aloud.”
After secretly completing the prediction, look at the spectator rather than the notepad. Let the suspense build, then reveal the page.
Common Mistakes
Writing Too Much
Long words and complicated numbers take too long and increase the chance of exposure.
Watching Your Thumb
Looking at the secret writing directs the audience's attention to the method.
Holding the Pad Flat
A flat or outward-facing pad may expose the blank page or the thumb movement.
Rushing the Reveal
A short pause makes the prediction feel established and increases the impact.
Practice Plan
- Practise drawing a circle, square, triangle and the digits zero through nine with your thumb.
- Check legibility after each attempt and adjust the graphite position if necessary.
- Rehearse in a mirror while keeping the pad angled away from the imaginary spectator.
- Add the spoken presentation and practise looking up during the secret writing.
- Record one complete performance from the audience's viewpoint before showing anyone.
Performance Tips
Confidence matters more than speed. The apparent prediction should feel like a minor action that happened before the main conversation began. Once the spectator names a choice, avoid repeating it several times or staring at the pad.
Perform the effect only once for the same group. Repetition encourages spectators to study the notepad, your thumb and the exact timing more closely.
