I was perusing YouTube and ran across a channel called "That's A Good Question."

They have a scientific answer to odd questions like "What exactly is processed meat?", "Can we stop an earthquake?", "Are invisibility cloaks possible?" or, as in the video above, "How do bikes stay up?"

I burned about an hour and a half watching the different videos. They range anywhere from two minutes to ten minutes but for the useless knowledge geek that I am, they are all very interesting and surprisingly make sense.

Give their YouTube channel a visit, you know, to give that water cooler conversation a boost.
