5. FemDefence Tampon Anita Ingmarsdotter, a Swedish woman, has patented an anti-rape device called FemDefence.
The FemDefence is an anti-rape device that would most likely give rapists the most painful experience ever.
The device looks like a standard tampon which can be inserted into the vagina. While the end that goes into the vagina is blunt, the end that is poking out would contain a sharp needle like pin which would prick the rapist's penis during the rape.
The needle has been designed in such a way that the wearer goes unharmed while the rapist would most probably develop a fear of raping anyone ever again.
