17 Things We Could Only Dream of, and Now They’ve Been Invented

Sometimes you think that it would be nice to have something new/useful/unbelievable and then you find out that this thing has actually already been invented. For example, a jacket that is good for a cool fall day and the freezing cold. And how happy drivers would be if there were speed bumps that they could cross without shaking. All of these things already exist.

1. This traffic light on the sidewalk is for pedestrians on their cell phones.

4. Sunlight activated color-changing boots

5. A robot that keeps plants alive
