Nothing But The Truth by Cameron Francis

Effect

Nothing But The Truth is a card-based lie detector routine. A spectator selects a card, and through a playful interrogation, a custom "lie detector" card set determines if they are truthful or lying. No matter their answers, the method narrows down to their chosen card. The routine ends with a visual transformation where every card in the lie detector set changes into their selection.

Full details

The trick includes a wallet-sized lie detector card set and a 21-minute instructional video by Cameron Francis. The video teaches the routine and multiple variations. The method relies on a card force, structured Q&A scripting, and a simple deceptive move for the finale. The original version locks into one outcome, but the 2.0 update allows for more flexibility with a second force card.

Who should consider the trick

This trick suits beginners and experienced performers. It works well for close-up, parlour, or stage performances. English-speaking magicians will find it easiest to perform, but non-English speakers can adapt the script. Those who enjoy interactive routines with strong audience engagement will appreciate this effect.

Information on how difficult it is to perform

The trick is beginner-friendly. It requires a card force, basic scripting, and an easy-to-execute move. The Elmsley count is used in the 2.0 version, which may need practice for smooth handling. The reset is quick, making it practical for repeated performances.

What magicians say

Sebastian Toca calls it a must-have for card magicians and mentalists, praising its ease of use and strong reactions. He notes the transformation ending consistently impresses audiences. Alex Kirk prefers the original version but acknowledges the 2.0 update adds flexibility. He highlights the interactive hook and audience misdirection as strengths. Kev G includes it in his essential routines, describing it as a fun and interactive packet trick.

The trick is praised for its commercial appeal, portability, and crowd-pleasing nature. Some reviewers mention the non-examinable lie detector cards as a minor drawback. Overall, it receives strong recommendations for performers looking for a reliable and engaging routine.
