The Mine Kafon should be another handy device that may help out in the war department. The said ball is wind-powered and looks like something which came out from a war or sci-fi movie.
Anyway, the Mike Kafon, designed by Massoud Hassani is quite easy to use. It just needs a push towards a mine field and then it triggers the mines (if any) existing and probably save the lives of some unfortunate soldiers too.
Each giant ball can reportedly clear up to 4 landmines and are said to be cheap to make. Check out the video.
