I am REALlY lazy. I just stomp on the side of the can with swift, and blinding violence, greatly reducing the volume inside the can, resulting in compressing the contents within the can.
Probably much less long lasting as refilling it with compressed air, but I am also going for violent retribution, and revenge against the man.
