Gary LeschinskyThird-grader Gary Leschinsky of Mahwah, New Jersey is a problem solver. He’s also an inventor.

To mitigate his own allergies, Gary invented a patent pending wearable device, the A-Watch for Allergies, which detects early symptoms of an allergic reaction and notifies an adult by sounding an alarm as well as via a text message. A-Watch has multiple sensors that can detect early symptoms of an allergic reaction such as itching, skin redness, increase in heart rate, and sweating. Using a GPS receiver, it can locate the child and the EpiPen. It also has a compartment for an allergy medication such as Benadryl so that it can be administered quickly.

"Six million kids in the U.S. have food allergies, says Gary, 9. “Children may not always understand or be able to explain that they are having an allergic reaction. This may delay treatment and lead to complications.”

Allergic Reaction and A-Watch: Wrong food eaten, Body thinks it is an invader, cells release histamine, body sweats, blood pressure goes down, heart beats faster, skin gets red and itchy, sensors activated alarm sounds, parent texted, epipen located

For a young inventor, Gary has already experienced his share of notoriety. He’s appeared on two TV shows, including “The Tonight Show,” where he shared his combination Nose and Earmuffs, and "The Rachael Ray Show," where he pitched the A-Watch for Allergies to the investor team from ABC’s “Shark Tank.”

He’s comfortable in the limelight and matter-of-fact about his burgeoning fame. "I started to invent at the age of 6. Some of my inventions are: Nose and Earmuffs, Safe Skewers, and a No-Spill Taco Holder," says Gary, who plans to take CTY's Be a Scientist course in New York City this summer. "'The Tonight Show with Jimmy Fallon' was a great once-in-a-lifetime experience.”

Gary is now collaborating with his brother on an invention, the Lung Exerciser for Assisted Living Folks or LEAF, which is designed to help people in assisted living communities improve their breathing with lung exercises. LEAF is a spirometer, a device used for measuring amounts of air inhaled and exhaled by the lungs. It powers its controller and display utilizing a user’s breath, and provides clear biofeedback and encouraging messages to its users based on strength or weakness of air intake and output.

Gary loves to invent “because I love to help people and make new things,” he says.  “I also want to inspire kids to invent because most kids think inventing is only for adults.”
