Teenage Boy Invents Device to Prevent People From Driving Under the Influence
Every 53 minutes, someone is killed in a preventable drunk driving car crash.
Though drunk driving decreased in 2014 (a fact Uber has cited credit for), 13-year-old Krishna Reddy sought to create a mechanism that would aid in the continuous reduction of this number, Yahoo reports.
Frustrated with the fact that a breathalyzer can only detect the amount of alcohol in an individual's system, the Texas teen came up with an apparatus that detects liquor, marijuana and other stimulants with the click of a button.
According to Reddy, his "DUI Detection Device" works by dilating a subject's pupils via the shining of a flashlight. Immediately after, the tester photographs the eyes with a digital camera. The teen's creative invention uses a toilet paper roll to concentrate the light as the camera photographs the pupil's contractions. Moments later, these contractions are documented via a software program that Reddy designed to measure the constriction of the pupils that occurred once the bright light shined on it.
The adolescent's invention is considered far more effective than the standard naked eye-to-eye examination due to its inclusion of numerical evidence that measures the pupillary reflex on a scale of milliseconds and millimeters. Because of this ability, it is able to pick up alcohol and drugs like painkillers, sleep aids and other amphetamines at the same time.
Reddy's unique invention landed him a spot as one of ten finalists in the Discovery Education 3M Young Scientist Challenge.
As part of the competition, Reddy is trying for title of America's Top Young Scientist and a monetary prize of $25,000. The finals will take place from October 12-13.
