It's in My Genes (Gimmicks and Online Instructions) by Michel - Trick

Turn a spectator’s freely chosen number, letter, and flag card into a surprising prediction drawn by your five-year-old son. In It’s in My Genes by Michel, the spectator sees all three choices pictured together in the child’s drawing.

Built for stand-up magic, this routine gives you a lively story to play on stage, in a parlor, for kids, or as an MC. You can also add an optional kicker: the drawing can match a spectator’s visible traits, such as glasses or a beard, and include their name on the back.

• Three audience choices: Spectators freely choose a number, a letter, and a flag card.
• Custom-made props: The set includes two plastic envelopes, one specially designed paper envelope, and a specially printed and prepared jumbo deck of flag cards.
• Prediction drawings: Two A4 printed drawing predictions are included, along with a packet of sticky notes and a black marker.
• Ready-to-perform instructions: A video download and PDF include the labels, drawing prediction, and envelope.
• Practical for shows: The routine packs small, plays big, resets quickly, and is described as easy to do.

The routine can be performed in any language by changing two labels. The matching drawing can also become a memorable souvenir for your spectator.
