This is interesting prop, it is best suited for bigger audiences and very versatile as it can be used for adults, kids but also for trade show performances.
The performer introduces an oversized image of a magicians top hat and opens it by folding the front down. It can clearly be see that there is nothing between the plates. A kid is then asked to draw an apple and the drawing is inserted between the plates. When the front is folded down again a real apple appears between the plates.
Any relatively small item can materialize by putting a drawing in the magicians “top hat”
