Aspiring scientist invents 'gun' earring for women's safety in northern India

An inventor from northern India has developed a new personal security gadget for women.

Shyam Chaurasia, 29, an aspiring scientist, hails from Varanasi in Uttar Pradesh.

He has developed a non-lethal 'earring gun' that can set off an explosion-like sound, but also send a distress signal to the police emergency number 112.

"The earring gun is rechargeable and reusable. It is made to tackle the growing reports of sexual violence in our country."

"We live in a generation where I believe every woman should feel safe being independent. This gadget will help them to come out of stressful situations just like a pepper spray," he said.

The smart gadget looks like a pair of earrings that can be worn by any woman.

On pressing a button, it alerts the police and sends them the current location without the need for operating the mobile phone.

There is an electronic trigger that sets off an artificial bullet filled with chilli powder in the direction of the perpetrator. The effective firing distance is 30 metres.

It generates a gunfire explosion sound that has a radius of one kilometre.

Chaurasia said the gadget can be built under five hours and costs around $6 to make one.
