Hold a square rubik in your hand and show it completely and even rotate its sides so that the audience realizes that it is a normal rubik, then we put the rubik in the box, remove the tube and press on the rubik, at this moment mysteriously the square rubik turns into a round (cylindrical) rubik that shock everyone!!!
