See C.ondoms That Could Detect STIs Invented By Teenagers

They might not have experienced s3x before, but they have created a solution for many adults who practice s3x.
A team of teenage inventors have revealed a condom capable of changing colour when it comes into contact with STIs.
The prescient prophylactic has a built-in indicator that alters its colour depending on what infection it picks up. This was revealed at the TeenTech Awards in London where it won the health category.
Called the S.T.EYE, the project was the creation of Daanyaal Ali, 14, Muaz Nawaz, 13 and Chirag Shah, 14.
