Force Change Bag
This is a natural and innocent looking prop, a mesh bag with a handle .
The contents are always visible but the bag is cleverly constructed to allow you to force the selection of small items that you put in the bag.
The bag could contain a deck of cards, shaken and mixed, and spectator reaches in to select a single card - it is your force card. Use just about any small object that you can put a dozen or so in the bag.
The fancy bag is totally handmade. You need one of these!
Works like what it looks like!
