Split Ghost Tube

You have a tube that has been lying around with you during the entire show. You open it by splitting it at the center to show that it is empty. You then close it and produce a bunch of stuff from it such as spring flowers, silks, sponge balls and a variety of such things. With this Split Ghost Tube you split open the tube at any time to show that it is empty and yet can produce from the empty tube at any time.
