Touchdown! Greaser!
If you want to see how the little spring loaded device is supposed to work, go to a junk yard and push it against the corner of a car/truck window near the corner. The safety glass will shatter into small beads. You may want to ask the owner first.
I'm sure @AggieMike88 won't mind if you bust up a few of his windshields.
