Here is a well-known marble puzzle (difficulty: hard).

 

The objective: the marble must be placed into the cup.

 

Rules:

  • The marble must rest on a relatively flat surface (table)
  • The marble may only be contacted by the cup (not by hands or other objects)
  • The marble must not fall off the table

Ideal for challenging friends or family (who can do it faster? who can do it at all?)

 

Assembly:

  • Connect the two hemisphere halves using the connecting piece (with a satisfying click sound :))
  • Finished

 

 

 

 

 

 

SPOILER

 

Solution:

  • Place the cup, open side down, over the marble.
  • Quickly move the cup using circular motions.
  • In the right moment, invert the cup.
  • It is not easy due to the cup's low height and shape, however, it is still possible.

Physical forces:

  • Centripetal force: The circular movements generate a centripetal force that directs the marble inwards once it is in motion.
  • Friction: The friction between the marble and the cup ensures that the marble does not simply slide away, but transitions into a controlled circular movement.
  • Air currents: Air movements within the cup can additionally aid in moving the marble.
