Who says inventions are only made by grown-ups and professionals? Over the years, children have also succeeded in making their useful contributions to the world. Here are a few inventions that came to life from the minds of young children.

Hero Helmet

Seven-year-old Samul

Meyer's invention is aimed at stopping people from riding their bikes or skateboards without using a helmet. The Hero Helmet features an inbuilt remote that controls a lock on the wheels which unlocks when the Helmet is being worn by the rider. Samuel says: no helmet, no bike.

Robotic Earthworm

The first thought that comes to mind is,why a robotic earthworm? Well, ten-year-old David Cohen had some useful applications in mind. He believed it could be used to find victims after a flood, earthquake or fire.The robot could get into small and dangerous places where search dogs and humans could not go.

B.E.A.C.O.N.

Fifteen-year-old Hannah Herbst's invention, which stands for Bringing Electricity Access to Countries through Ocean Energy, was inspired by her pen pal who lives in Ethiopia and did not have access to lights.So she came up with B.E.A.C.O.N,which absorbs energy directly from ocean waves. Her invention won the“Discovery Education 3M Young Scientist Challenge”in 2015 and other numerous awards.

Portable Wheelchair Controller

At only eight years old, Amelia Fox created the invention to help lift people in and out of their wheelchair. This invention was not just born out of the desire to create something. Amelia developed this controller for her brother,who had just got hip surgery and needed the wheelchair to move around.
