Let just say this kind of wall:skywolfblue said:Define "solid wall"? Drywall, 2by4s, Concrete Block wall?SweetShark said:Do you know any kind of chocolate so hard that can break a solid wall?
I think a large mallet/hammer of hard chocolate could go through the wood, but I really doubt even the hardest chocolate frozen would be enough for concrete. Maybe a poorly done/loose ordinary clay brick wall?
You know what this calls for? A cannon that fires chocolate cannonballs! Mythbusters should totally do this!

As you said already, there is a chance to break this kind of wall, am I right?
