Tie one-end of a shoe-lace tightly around the klickie's head and tie the other end of the shoe-lace to a door knob.
In a deep karate stance, give the klickie a jerk.
(I learned this off Playmoboard but don't remember the originator).
I like the rubber band idea using tongs better though, and will give it a try. I want this process to be easy, not lead to sore muscles, mashed hands, or too much sweat. The doorknob-shoelace method I use can hurt your hand if you don't grip the klickie hard enough and it slips free. Otherwise, from the karate stance, you can add your hips to the jerk-motion, so the effort does not feel straining.
