I chose this effect from an online dealer, as a substitute for an out of stock item. It fits in with my 'easy to carry, anytime, regular object' effects. I liken it to David Acer's 'Spare Change'. Acer's effect uses two coins, and likewise, is perfect for whenever you get asked to perform a trick. Zinger, which is a different effect, is like 'magician's choice' using coins-as opposed to unusual cards, a pen/pencil, envelope, and prediction card. Not a heavy duty trick, but a coincidence that will definitely make people wonder. Easy to do, and I think it"s a nice, easy lead in to more attention getting effects in a spontaneous situation.
