Description

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.
