Enchanted Ring
Everything is clearly shown. The ring is placed into the slot in the cube. The pin goes through a hole in the cube, locking the ring inside the slot. The spectator can see everything, and is now given the chance to hold onto the materials.
While these are in the spectator's own hands, you are able to reach over and instantly separate the ring from the cube. It passes right through the pin -- the spectator can examine everything. The pin still goes through the cube, but the ring is obviously free. Nothing is added or taken away -- a close-up miracle. A veritable banquet of magic. You'll love this devilishly clever piece of quality apparatus. A fine piece of workmanship.
