Okay, get an aluminum can to represent your tower.
Empty the can of its contents.
Place can on table and get a pen or your finger will do but be sure to get it out of the way quickly.
Place palm of hand flat on top of can and apply a large amount of pressure downwards and hold it there.
Take your pen and use it to poke the side of the can, distorting its structural integrity.
See what happens? All that downward pressure collapsed the can neatly in one direction, not to the sides but straight down.
How is that?
