This effect was made famous by Harry Houdini, an illusion he called Metamorphosis (means "change"). Also traditionally called a “Substitution trunk” (Sub Trunk for short), the magician displays a beautiful steamer style trunk. Volunteers from the audience can assist the magician by moving the trunk in place, opening the hinged lid, and giving the box a thorough inspection.
 
Next the magician displays a pair of handcuffs or other wrist restraint device, and a large cloth bag.
The magician's assistant enters the trunk and then is handcuffed. Next she enters the bag and one of the volunteers tie the bag closed with a piece of rope. The assistant bends down inside the box, the lid is closed, and the trunk is locked. Lengths of rope can then be used to tie around the box in different directions to further make sure the lid can't easily be opened. Next the magician hops-up on top of the trunk and raises a tubular curtain. On the simple count of three, the curtain is dropped, and the assistant is now standing on top of the trunk! The trunk is opened, and the magician is found in the trunk and handcuffed inside the cloth bag.

This is our Deluxe Substitution trunk. It is made from the finest luan and is covered with natural wood-looking laminate. It is finished with beautiful hand polished metal trim and hardware. It is professional through and through. Note that the curtain, bag, and handcuffs are not supplied. These are additions that can be supplied for a reasonable price.
