Mine Kafon is a low-cost landmine detonator. A spherical device made out of biodegradable plastic and bamboo, it's light enough to be blown by wind. But it is also heavy enough to set off landmines as it rolls over them. "With each detonation the Mine Kafon loses just one or two legs so it could potentially destroy three or four landmines in one journey." Support us on Kickstarter.
