Potato chip can

I get so annoyed when I'm eating a can of potato chips. I can reach the top ones fine, and then the bottom chips just hide there. It takes me so much time and effort to grab those chips. So instead of my hand going to the chips, why not have the chips go to my hand?

The bottom of the can could be made adjustable so as to move up and down. That way the potato chips could be raised up so that you wouldn't have to reach all the way in.

Can design
Potato chips are oval, and the can is circular. Does this make any sense? Why can't the can be elliptical? Another benefit to the elliptical cans is that they waste less paper to wrap them, and they fit on a truck better.
