Leaning Tower

Try as we could we could not straighten out the tower... When i build anything it always comes out slightly leaning as well... i wonder if i am secretly a genius builder??? they say that Galileo dropped two cannon balls of different masses from the tower to demonstrate that their speed of descent was independent of their mass... they stuck a plaque up to commemorate him doing it ... a guard wouldn't even let me drop two small rocks off....
