This innovative idea was thought of by 3 students, Daanyaal Ali, 14, Muaz Nawaz, 13 and Chirag Shah, 14, pupils at Isaac Newton Academy in Ilford, Essex, who wanted to “make detecting harmful STIs safer than ever before” without the need for invasive tests about 3 years ago.
The proposal won the trio the top prize in the U.K.’s TeenTech Awards, and they have already reportedly been approached by condom companies.
The idea, however, is not without its imperfections. It seems unclear whether the STIs would be detected in just the user’s partner or also the user as well. In addition, there’s the awkward question of what would happen if the condom came into contact with two or more STDs—not to mention the logistical difficulties of figuring out a way to determine the color with sufficient opportunity to make use of those findings.
