How To balance a can ?

Can is the thing that we encounter on a daily basis. Can this drink offer anything else? It can serve as a box for pens or it may also entertain us and our friends.

Take the empty can and try to put it on the sloping part of the bottom. What will happen? Can falls. Why? Is it possible to stand on the side?

Try it. Take can, fill it approximately half with water and try to put it back on the sloping part of the bottom. Amazing, tin stand on the side.

How is it possible? The fact that can is filled with water, there is a shift of the center of gravity and therefore can happen. Physics is beautiful, is'nt it? :-)
