how to break a computer?

A  hammer does a real good job or water on a keyboard. Wont tell you what a shotgun does to a computer!!

Drive over it with this

Drop it off a 14th story balcony !!! I did that to an ex's gutiar when I was in my early 20's. It worked and felt awesome at the time :) . I'm much calmer now though and don't condone that type of behaviour anymore . Never mind then.
