This game i learnt from friends on gaming forums... there are other variations of this game and if there are on this forum then i do apologize. anyway the game goes like this:
There is a hill and you have to do everything and anything to capture it... once you have captured it you simply say "My Hill" Starting....NOW!
It remains perfectly normal because of the equal forces pushing on it from the inside and the outside and, other than a severe rumbling sound, leaves the hill unharmed.
