""Kids are natural innovators,"" said Jon Dudas, who used to work for the U.S. Patent & Trademark Office but is now the president of FIRST, an organization designed to help foster innovations by kids in science and technology.

Dean Kamen, the founder of FIRST and the inventor of the Segway personal transporter, got his first patent when he was 17 for an insulin pump. ""His mom had to sign the papers!"" Dudas said.
One of the youngest inventors, Dudas recalls, was just two. ""Her parents had sort of sectioned off a place where she couldn't open the cabinet doors. She used suction cups and an extension,"" Dudas explained. ""Her parents thought it was a neat idea -- to use for people in wheelchairs with limited movement,"" he said. She had a patent by age 4!
Kids have been inventing things for hundreds of years and now, thanks to organizations like the Liberty Science Center, FIRST and By Kids, for Kids they're feeling more inspired and more confident to invent. And, turning their products into sales is becoming more of a reality.
Here are 5 cool and inspiring inventions by kids.
Smart wheel
The Inventioneers are a group of six teens from Londonderry, N.H., and, while some of them can't even drive yet, they've invented a device to help curb distracted driving.
It's called the Smart Wheel and it stands for ""Safe Motorist Alert for Restricting Texting, Tweeting, Typing, Touch screens, and Touch ups,"" said Tristan ""T.J."" Evarts, a 15-year-old member of the Inventioneers. It's basically a cover for your steering wheel with sensors and LED lights that determines when you don't have both hands on the wheel.
The kids, winners in First Robotics' ""First Lego League"" competition for several years running, have a provisional patent on the device, one of four patents the teens hold on various inventions.
Popsicles
Sometimes inventions by kids are amazing technological innovations and sometimes they're just plain practical ideas that make you wonder, ""Why didn't I think of that?""
The Popsicle , that staple of summer, was created in 1905 by 11-year-old Frank Epperson -- by accident! Epperson had left a mixture of powdered soda, water and a stick in a cup on his porch overnight -- and it was a cold night. He woke up the next morning and it was a frozen treat on a stick.
He initially called it the ""Epsicle,"" which was quite popular with the other kids at school and later his own kids. They kept asking for ""Pop's 'sicle"" and that, Jimmy, is how the popsicle was born. He got a patent on it in 1923 and then sold the rights to a bigger company. Today, the brand is owned by Unilever and they sell more than two billion Popsicles every year.
Here's another fun fact: The double popsicle was invented during the depression so two children could share it and it would only cost one nickel.
Wristies
Don't you just hate when you're outside and, even though you're wearing mittens, the snow gets down the sleeve of your coat?
Most of us just complain about it but one winter's day, 10-year-old KK Gregory was outside building a snow fort and decided to do something about it. She created the first pair of Wristies, a fingerless glove that goes halfway up your arm, keeping your wrists warm and dry. You can wear them with or without mittens.
Wristies were a hit with her Girl Scout troop, so she decided to get a patent and start her own company.
Ear muffs
Speaking of things that warm you up, ear muffs were also invented by a kid.
The year was 1873 and 15-year-old Chester Greenwood was testing out a pair of ice skates. He was getting frustrated because his ears were so cold. He tried wrapping his head in scarf but it was too bulky and too itchy. So, he took wire and bent it into two round loops, then asked his grandmother to sew fur on them. He connected them with a steel headband and got a patent on his invention -- Greenwood's Champion Ear Protectors.
He sold a ton of them to U.S. soldiers during World War I. To this day, Greenwood's hometown, Farmington, Maine, is known as the Ear Muff Capital of the World. They even have a parade every December to celebrate his birthday -- and his invention.
By the time he died in 1936, Greenwood had more than 100 patents, including a tea kettle, an advertising match box and a steel-tooth rake. ""There truly was a lot more to Chester than just being the inventor of ear protectors,"" wrote Nancy Porter, a volunteer with the Farmington Historical Society.
