An effective little trick usually follows that of the Cut and Restored String in the form of an egg being put into a small bag. A magic pass is made over the mouth of the bag, which is then turned inside out, stamped upon if necessary, and slapped all over to show that it is quite empty and that the egg has disappeared. At will, and with another magic pass, the egg reappears from the bag when it is turned over, mouth downwards.

The secret lies in the fact that the bag, which is of some opaque material, and is nine inches deep and six inches broad, has one of its sides double. The easiest way to make such a bag is to take a piece of cloth six inches broad and 24 inches long. Fold six inches of one end over and then turn the other end to where the cloth has been folded. Stitch up either side, thus making a bag.

When the egg is put in, it drops to the bottom of the bag. When the performer dips his hand in again to take out the egg, in doing so he slips it into the pocket formed inside, and leaves it there, bringing his hand out empty and from which the egg has disappeared. The bag being turned inside out does not expose the egg which is in the inner pocket. When treading on or slapping the bag, care should of course be taken to miss the egg.
