An eighth grader got tired of one really annoying problem. His hearing aid batteries kept dying too fast. Since Ethan had been wearing them since he was four years old, he decided to turn that frustration into a science project. He started experimenting, testing battery after battery, using little robotic bugs for the project. He discovered a simple solution almost nobody knew. If you peel the tab off a hearing aid battery and wait five minutes before putting it in, the battery can last up to 85% longer. Doctors were stunned. His audiologist started telling every patient about it. The clinic even added Ethan's discovery to their official hearing aid instructions. What started as a project that Ethan hoped would get him a good grade ended up saving millions of people money every year.
