17 practical inventions and re-worked designs set to change the world

Most inventions are designed to be practical, even if they sometimes look like they're from another planet... Their creators have often spent years coming up with an idea and prototype. Their reasons are many, but in the majority of the cases, it's because they want to simplify their lives and also to potentially help thousands of users.

So in honor of these creative geniuses, here are 17 inventions that have revolutionized the lives of their users.
