The illusion Melinda Messenger performed to promote the Health Lottery is called the Mismade Girl. The normal illusion sees the assistant inside sliced into four pieces, but this version sliced Melinda into five, tying in with the Health Lottery's "five boxes" playing style.
Melinda had been on Loose Women the previous year to promote another magical advertising campaign - on that occasion being beheaded in a guillotine trick while dressed as a French maid, for a Walker's Crisps advert.
