30 Things That Science Hasn’t Figured Out Yet

How Do Bicycles Stay Upright?

18. How Do Bicycles Stay Upright?

Have you ever given a push to a bicycle that has no one riding it, and seen that it stays upright for way longer than you’d expect it to? Well, this phenomenon has mystified physicists because it doesn’t seem to follow the regular laws of motion.

Some scientists ventured a couple of explanations involving a phenomenon called the caster effect. Others say that it could be due to a gyroscopic effect that’s much like the way a spinning top stays upright for a long time. 

But both of these hypotheses were debunked by scientists at Cornell University when they managed to construct a bicycle that stayed upright without recording either of these two phenomena.
