My wife has worked very hard to get our kids into a night time routine so that they’ll go to bed without too much fuss. Â Somewhere along the way, they decided that they needed to have flashlights. Â We couldn’t stand to walk into the room and find the kids asleep with the batteries dead on the flashlight. Â So for Christmas we found some Wind-Up flashlights and they have been pretty awesome. Â Well, the other day I saw a great concept from designer Qian Jiang, Wind-Up Batteries! Â Get more info atÂ Yanko Design.
