A Double Tour by Gabriel Werlen & Marchand de trucs & Mindbox

Two devastating impromptu miracles of mentalism!

In A Double Tour, Gabriel Werlen unveils two stunning effects and secrets until now reserved for only a handful of professionals.

Effect 1: Ultimate Free Will

A prediction is placed in full view from the very start.
You present three objects to your spectator and invite them to decide:

Their choices are completely free, and they may change their mind as often as they like. When the prediction is finally revealed, it perfectly matches their exact decisions—every single time.

Effect 2: Wisps

You invite your spectator to cross the boundary between imagination and reality. Holding your closed fist before them, you ask them to imagine a handful of matches and freely decide how many they see.

When you open your hand, the impossible happens: inside are precisely the number of matches they imagined.

This original effect breathes fresh air into any performance. The physical manifestation of a thought is both beautiful and deeply impactful—subtle in method, yet stunning in effect.

Bonus Effect: Heads I Win, Tails You Lose

As an extra gift, Gabriel shares a routine from his book Iceberg.

You challenge your spectators to a coin toss game you can never lose. The twist? The coin only exists in their minds and they themselves decide how it lands.

A bold and brilliant evolution of the classic Free Will principle, this effect has fooled and delighted some of the world’s greatest mentalists. When you uncover the ingenious secret, you won’t be able to resist smiling yourself.
