A Jump Rope is Fun – But It Also Can Make Light


I love to jump rope.  I love love love it.  I grew up in an area in central Illinois where Double Dutch was THE grade school recess activity of choice – either jumping or watching.  I grew up in a financially poor area, but the kids I grew up and went to school with were rich with creativity – and when there was no rope to jump, they collected and tied bread bags together and made jump ropes with that.

I just read about a toy idea that uses kinetic energy used in jumping rope to charge an LED flash light – the toy also monitors how many “jumps” you’ve done, and how much charge you’ve given to the light.  Kinetic energy to electrical energy – I already like this thing and it’s still in concept phase.

Check out some images of designers Hyun Joo Lee and Eu Tteum Lee’s jump-rope-flashlight:

Thanks, Inhabitots!

Jump rope has come a long, long way from Butternut bags, hasn’t it?
