Kinetic Flashlight
I keep a kinetic flashlight at work - the kind u shake to charge the battery - so I can watch beneath my desk if I need to rewire my computer, printer, or phone. Final time I discovered my flashlight dead, I was alone in the building, it was late, and I was feeling a little lonely, so I tried recharging it a fresh way ... and it worked! I hope u have as much joy watching me crank it up as I had doing it!
