It has some rigidity, right? Take the other cans and squash it flat. Now, it is much more easily bent and twisted, right?

For tubing, this works up to a certain point. Tubing can be so large and thin that it is no longer practical to use, because it cannot be easily welded, is too bulky and easily dented.

Oh ok. The soda pop example helped.
