Mumbo Jumbo Change Bag With Zipper by Ickle Pickle Products, Inc. - Trick
Effect: An object is dropped into the MUMBO JUMBO and its GONE! Or, if you wish, use it to produce four hundred and seven 12" silks, two hundred and nineteen 1" sponge balls or seventeen sets of Nesting Wands so that you can then call up eight-five people to assist you.
Why a Zipper? Simply so you can start with the bag unzipped and when you drop something in, it naturally falls out. Or drop something in and then unzip to convince your audience the Mumbo Jumbo is just a bag. The Zipper basically gives you an extra option.
