Comic Book Test & Stag Mag-ic
A page, ripped from a comic book (or stag magazine), full of quirky advertisements is shown to the audience. A spectator is handed this page and asked to select an advert, which is torn from the page and pinned to a board.
Attention is then drawn to a sealed package that has been on view the whole time. It is opened to reveal the product advertised on the selected advert!
