Editor's Note: Looking for more engineering creativity? This page features videos curated in 2025. For our 2024 collection of ingenious inventions, head over to our previous roundup here.
Engineers have some of the most out-there and smart ideas that boring minds like myself would just never think to try—which is why I'm an editor and not an engineer. From experimenting with what-ifs of chemical reactions to Rube Goldberg machines for the most basic tasks to creating a new concept for a product, it's never a dull moment when seeing inside an engineer's mind. So take a break and watch this collection of videos that put the what-ifs into practice from industry professionals and engineering enthusiasts alike.
