11 Simple Yet Thrilling Invention Ideas For Kids

Thomas Alva Edison said, “The greatest invention in the world is the mind of a child.” Childhood is the peak of imagination. If your child is a master of DIY projects or is just learning to simplify complex tools, it reflects their interest in innovation and creativity. Some kids also turn their interests into successful businesses. Dominic Wilcox, an artist and inventor from the UK, came up with the brilliant idea of asking children to invent something. He later created a new website called Little Inventors, too. He says in his blog, “Back in October of 2015, I returned to my hometown of Sunderland and asked 450 primary school children in the city to think up and draw their invention ideas. Then, I asked skilled local makers to make the best ones into real things (i).”

If you want your little engineer to bring their big ideas to life, here is an interesting collection of invention ideas for kids. These ideas would make your child think out of the box and help them with school projects.
