Mental Pop by Nick Lathrop

Mental Pop is a stunning prediction effect that blends mind reading with an unforgettable visual climax.
A spectator merely thinks of any place—no forces, no fishing and no stooges. The decision truly theirs.
From the very beginning, another spectator has been holding a sealed balloon in full view. It has never left their hands.
When the moment is right, the balloon is dramatically popped.
Inside is a single prediction.
It matches the freely thought-of place.
The revelation is impossible, unexpected, and leaves audiences with only one question: How could that have been inside the balloon all along?
Mental Pop, Nick's handling of the Tervil plot, is designed for close-up, parlor, and stage performances, combining a clean premise with a memorable visual ending that audiences will talk about long after the show is over.
