A 12-year-old Tennesee boy says he's invented a gadget that could help prevent hot car deaths.

Andrew Pelham explains his award-winning invention, which he has named the "EZ Baby Saver."

"It's not really that snazzy or anything," Andrew admits. "You loop it over, and as you're getting in, you attach it to the car handle."

Made from rubber bands and brightly colored duct tape, Andrew designed the device to keep parents from accidentally leaving their children in hot cars.

"When you're getting out of the car, you see this bright, flashing rubber band. You're like, 'Oh, my child is still in the car,'" he explains.

It's simple, yet genius, and people love it. Andrew's website for his invention, ezbabysaver.com, has gotten thousands of views and shares on Facebook.

"It was something crazy, like 26,000, and there were people from all over the world — people from Germany, Australia — even people in Japan looking at it," Andrew said.

The 12-year-old made it for a youth inventors contest, and Andrew won $500 for his invention.

"This was the third concept I had," Andrew explained. "The first one was something having a flag that popped up, and the second concept was about tying something to the child, which was not a very good idea."

Andrew says he isn't in it for the fortune or fame.

"I don't really care about having the publicity," he said.

Instead, he put directions on his website so others can make their own EZ Baby Saver.

"I encourage people — maybe, if you don't want to make one, and you don't think the idea is very good, then don't make one — but at least try to be a bit more careful when putting your kids in the car," Andrew said. "If you know that your day is going to be out of whack, if you're taking your kid to a birthday party or something, then you might want to be a bit more careful."
