Linked Rings (Posted on 2004-05-29) Difficulty: 2 of 5
Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.
  • The red ring is "behind" the yellow.
  • The yellow ring is "behind" the blue.
  • The blue ring is "behind" the red.
Still, while none is intertwined with another, it is impossible to pull them apart.

Is this a paradox?

Can this really be built?

The red circle is fully underneath yellow circle (as seen by crossover points)
The blue circle would have to be pulled apart to be inserted as it goes over the yellow ring, underneath the red ring and then back over itself for support. On the reverse side the red circle is being supported by the yellow and hence why it is self inter-locking.
