Topology

To a regular person, these objects don't look similar. But according to the science of topology, a modern area of geometry which studies all different types of spaces, these objects belong in the same group.

EOS Chapstick

 

Nutella®  Jar 

When two figures belong in the same group, they are referred to as topologically equivalent. The objects of study are most commonly organized by figures that can be stretched, bent or molded into different shapes without cutting or puncturing, and vice versa.

So, by those standards, the EOS and Nutella® would fit in the same category, because they have both have a shape that can be changed to the other without cutting puncturing. (~IR1)
