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?

if the red ring be behind the yellow and the yellow ring behind the red ,so the blue ring must be on the red ring ,on this state we can pull them apart!!!!
