13 Year old has a brilliant idea to stop drunken people from driving

Consumption of alcohol and then driving is simply the worst combination which does not go together. The human brain has the ability to deal with numerous things and process limitless data all the time. Consuming alcohol disturbs concentration and one’s ability to make quick conclusions on the road, react to changes in the environment and perform specific, often problematic moves behind the wheel. When drinking alcohol, u should avoid driving as it becomes not only dangerous but also potentially lethal. Click here to learn more about how you can get penalised for a DWI.


Persons driving under the effect of alcohol are generally mentioned as drunk drivers, drunken drivers. When some is charged with this as a crime, it may either be denoted as a DUI (Driving Under the Influence) or a DWI (Driving While Intoxicated), if you have been charged with a DWI or a DUI, it would be a good idea to get a lawyer such as this philadelphia criminal lawyer, however depending on where you live there are many different lawyers for you to use.

1 Drunk driving

In 2013, 10,076 people were killed and approximately 290,000 were injured. Each crash, each death, each injury impacts not only the person in the crash, but family, friends, classmates, coworkers and more. If you have been in an accident involving a drunk driver then you should look into law firms like this Langley car accident lawyer to see if you can get compensation for your accident. Drunk driving costs a lot of money each year. Even those who have not been directly touched help pay the $132 billion yearly price tag of drunk driving. But together we can eliminate drunk driving.


According to “Why drunk drivers may get behind the wheel”, a Mental Health Weekly Digest article, “[a]lcohol-related motor vehicle accidents claim 17,000 American lives each year- the equivalent of one death every 30 minutes. An increase of blood alcohol concentration (BAC) of 0.02 percent doubles the relative risk of a motor vehicle crash among 16- to 20-year-old males, and that risk increases to nearly 52 times when the BAC is between 0.08 percent and 0.10 percent, the legal limits in many states.

2 The boy

Krishna Reddy, a 13-year-old American kid of Indian origin from Wichita Falls, Texas has created a device that can state when a driver has consumed alcohol or used other drugs just by seeing how dilated his or her pupils are.

Reddy is one of 10 final contestants in the Discovery Education 3M Young Scientist Challenge, which is an annual challenge for the designation of America’s Top Young Scientist and a $25,000 prize.

3 The competition

The Young Scientist Challenge is a youth science and engineering competition managed by Discovery Education and 3M for middle school students in the United States, which is comparable to the European Union Contest for Young Scientists. Students are tested each year on their ability to create a 1-2 minute video specifying their idea for a new kind of invention that is envisioned to answer a problematic circumstance in one of three given categories.


From all the entries, ten finalists are chosen annually to work alongside a 3M scientist in a summer mentorship program and they also get to take a trip to the 3M Innovation Center in St. Paul, MN in order to contest for the grand prize of $25,000 and also for the title of “America’s Top Young Scientist.”

4 How the instrument does works

As a reflex action, our pupils are designed to get narrow in order to filter the amount of light that gets into our eyes. That’s the reason why we look directly into bright light; our pupils get smaller in order to let less light enter in our eyes and when it becomes dark, our pupils dilate and get bigger in size to let the maximum light in for us to see better. This effect is called the pupillary reflex.

While some kind of drugs, like alcohol and opioids, causes our pupils to contract, others, like LSD, mushrooms, and cocaine, cause the pupils to widen. Reddy made a device consisting of just three things: A digital camera, a snakehead flashlight, and a toilet paper roll in order to take benefit of this reflex of pupils of eyes.


The device works in the following way:

When the flashlight is kept up to the eye, the toilet roll helps to guide the light beam straight onto the pupil. At the precise moment, the digital camera is programmed to take video of the pupil as it constricts.

After that, the video is viewed using a piece of software code wrote by Reddy. The computer and the device process the amount of contraction of the pupil when the light is shone on it.

5 The video

Here is the video that Reddy submitted to the competition in which he explains how the thing works.


Until now it can only be used to tell whether a person has been drinking, doing recreational drugs, or if they’ve used certain banned painkillers, sleep pills, or amphetamines. That because the pupillary reflex occurs on the scale of millimetres and milliseconds, the device proves much better than when compared to the naked eye at sensing a drunk or compromised driver. Whether this device will prevent people from getting behind the wheel when intoxicated is unknown. Many incidents of people driving under the influence are of teenagers, who are a difficult age range to stop from consuming alcohol due to wanting to ‘fit in’ and the ability to fake their age through fake id sites. Perhaps one day this ongoing issue will be tackled, but for now, this device is another step in preventing driving with illegal substances in the system.
