Shake Light 40 Rechargeable Flashlight
Charge this flashlight by shaking it
I know that there are a lot of flashlights on Cool Tools, but this one fills a different niche. It is rechargeable by shaking it. Shaking it sends a magnet through a coil and that charges it. It was given to me about 10 years ago and is still going strong. I leave it on my desk and give it a 30 second shake while waiting for a boot-up or the like and it stays at full brightness. If I forget to charge it for a month or two I shake for 30 seconds it comes back to life, and if I shake for a minute then it is back to full brightness.
Because it is clear plastic it is a good example of how electricity is made. Kids love it.06/3/19
