The Mine Kafon Ball is a large wind-powered device, heavy enough to detonate landmines as it rolls across the ground. Massoud Hassani drew inspiration for the project from his childhood growing up on the outskirts of Kabul, where he would play around the minefields with homemade, wind-powered toys. The Mine Kafon Ball is approximately the height and weight of the average man, allowing it to trigger landmines as it rolls across them. The core is a 17 kg iron casing, surrounded by dozens of low-cost bamboo legs; each capped with specially designed compliant plastic “feet” which can adapt to rough terrains. The ball is equipped with a GPS unit that maps the route the Mine Kafon Ball has taken, allowing data to be utilised by local communities and others.
