A change bag is a magical switching prop used in the art of illusion, sleight of hand, and mentalism. A change bag is typically made of fabric, often with a secret compartment or mechanism that allows objects to be discreetly added or removed during a performance. Some change bags are made of clear cellophane which adds to the deceptiveness. Magicians use the Change Bag to perform tricks where items seem to disappear, transform, or change inexplicably. The bag’s design enables swift and seamless manipulation, creating visual illusions that captivate audiences. The versatility of the Change Bag lies in its ability to accommodate various sizes and types of objects, offering magicians a wide range of possibilities for their magic routines and mentalists a versatile utility forcing gimmick. This deceptive forcing tool enhances the mystery, wonder, and even hygiene of mentalism performances because the mentalist will often fill the bag with billets (small bits of paper with writing), then dangle the bag from the end of a pole, thus offering a spectator the chance to reach in the bag and grab a random billet. In the skilled hands of a Master Mentalist, the change bag appears so innocent that the audience will never remember any bag was in play during the magic act or mentalism performance.
