This is the Mine Kafon By Massoud Hassani. Hassani, who grew up in Afganistan, has figured out a way to detonate the mines in his town so local people can use the land safely. He has designed a GPS integrated Mine Kafon Ball that rolls over mines and detonates them. The ball will not explode when the mine goes off, it will continue to roll to the next mine to release the detonation. The ball is constructed of three parts, the spherical core, 70 bamboo legs that stick out from it, and black round surfaces for the feet. Click the link for more info and a video.
