Whilst in high school and college, I was never one to sit around wondering, “Why am I not getting laid?” I knew exactly why. Here it is.
I can’t help but drop some stats to reinforce the water twirling video. (This was the last post, see that first.) Ladies, hold your responses, I know you’re turned on.
The question was raised, “If the water is NOT swirling when you pull the plug in a basin, won’t the coriolis force make it twirl the same way every time?”
My conclusion. “No. It’s random.”
Over the course of several days, I (or my students) would fill the same tub seen in the video with water, and let it sit for a minimum of 6 hours (often more). Then we’d pull the plug from the completely still water. We did this 14 times. And saw some minor surprises.
Of those 14 times down the drain……
3 times it spun clockwise
2 times it spun counter-clockwise
7 TIMES IT SPUN FIRST ONE-WAY, THEN REVERSED AND WENT THE OTHER (I did not record which way it spun first)
1 time it had no spin at all.
I have no idea why it would spin two different directions on the way down (conservation of angular momentum does not seem to be the answer). But I am reassured that the coriolis force is NOT favoring it to spin one way over the other.
Ladies, feel free to leave your digits on the comments page. I know how hot that just was.
PS. Special thanks to my two physics classes for providing the labor of this great feat in science.

I don't believe your lies. Didn't the Simpsons already prove that the water spins different ways on each side of the equator? They even have a big machine in the U.S. Embassy in Australia to make the water spin the American way.
Awesome. I'm glad you took the time to figure this out for all of us. Now that it's out your system, go get laid. hehehe.
That is an awesome experiment. Now that you have blown the myth doors wide open, BY THE POWER OF GREYSKULL I command you to determine if ice cubes form faster if using hot water in the tray vs cold water.
