One of my favorite Boettcher/Pohle effects, this is a fooler using beautiful props that are very cleverly designed. A baffling routine where the spectator places a large block with different colored sides into a decorative wooden container with lid. Amazingly, you first reveal the color on top and then make the cube magically turn over inside the wooden box!
For a killer ending, the block is placed back inside the case which is again closed. When the lid is removed this time, the block is gone … having penetrated through the table top! This phase would fool many magicians as it uses a unique method that is very convincing.
