Debbie McGee spent many nervous moments shackled inside this box as magician husband Paul Daniels skewered it with spikes.
She lived to tell the tale and now she is putting the Geometrix illusion device up for sale, hoping it will perform a vanishing act of its own – going, going, gone at auction next month.
The box, one of Daniels' most famous illusions, is among a treasure trove of his tricks, costumes and props that is expected to fetch around £200,000.
