The drone that sniffs out landmines

This teen wants to rid the world of landmines

Landmines are an invisible danger – one which causes many deaths and injuries across the world. One Indian teen has found a way to safely deal with them – from the air.

It was a video that sparked Harshwardhansinh Zala’s life-saving idea.

The young Indian inventor saw a YouTube video where soldiers were trying to defuse a mine. The mine exploded suddenly, injuring several of them.

Harshwardhansinh thought there had to be a way of locating and dealing with mines that didn’t put people in danger. His solution? A drone that could snoop for mines without setting them off, then drop a marker to allow mine clearers to detonate them safely.
