About this 3D model

International Edition - This Model is designed for Euro 1 cent A participant is asked to lift all three decks and then the top deck alone. The participant will think the top box weighs more than all three boxes combines. How does this work? Charpentier, a French physician, discovered this illusion over 100 years ago. The illusion occurs when a person underestimates the weight of a larger object (Three decks) when compared to a smaller object of the same mass (Top deck).The top deck is filled with 84 pennies and the bottom 2 decks are hollow. Most of the weight is located in the top deck. The mind will trick you every time.Great illusion for the class room, team building events and showing friends.
