Get up from the computer and go get your keys. Yes, right now. (well....after you're done reading so you know what else to do) Get in your car, drive to the store and buy a bunch of tin foil pie plates. Go back home, fill them 1/3-1/2 way with water and put them in the freezer. When they are nice and solid, remove from freezer and go to your driveway or patio. Either one will do so long as you have a hard, solid surface such as concrete. Remove the ice from the pan and SLAM it on to the ground. Relish in the sound of something breaking that isn't causing actual damage and will melt in a short amount of time.
