These two YouTube videos played in tandem tackle age-old directional water flow myth

You’ve no doubt heard the saying that water in the northern hemisphere flows in the opposite direction it does in the southern hemisphere. But have you ever stopped to question the science behind whether or not that’s actually true?

After roughly three years of planning, the gang behind two of YouTube’s top science channels – Smarter Every Day and Veritasium – recently put the theory to the test. Seeing as Destin lives in Huntsville, Alabama, and Derek resides in Sydney, Australia, the two decided it would be fun to create two separate videos designed to be played in tandem.

Each clip complements the other in terms of dialogue, music, effects and so forth. I must say that this is one of the more creative YouTube projects I’ve seen in a while (not to mention the fact that I actually learned some stuff in the process). Job well done, guys.

They made the Internet that much cooler! Fun experiment and good Youtube channels any way that you look at it.

Yes, I think they showed that you can make the water go any way you want, so it has nothing to do with which hemisphere you are in.

The coreolis effect is real but so small that it has no real-world implications. Experiments to detect it require extremely controlled environments.
