Though it looks like a weapon from a generic machines vs man sci-fi movie, the Mine Kafon is actually a genius landmine clearer. Designed by Massoud Hassani, all you have to do is push the tentacle ball into a field of landmines and it can trigger mines to safely explode.

One of these giant balls can clear up to 4 landmines and are pretty cheap to make. I'd love to see it in action. [Callum Cooper Vimeo, Massoud Hassani]
