I spill my coffee a lot and I always wonder why I never seem to learn. I mean, you would think I would be pretty good at drinking coffee by now, right? Well, science says that it's not just me, and we humans are biologically built to spill our coffee!
I just read this article on Science saying that a team of mechanical engineers at University of California Santa Barbara has been researching why people spill coffee. The findings that they published in Physical Review E say:
"A fluid's back-and-forth movement has a certain natural frequency, and this is determined by the size of its container. Everyday mug sizes produce natural frequencies that just happen to match those of a person's leg movements during walking."
So, my conclusion is: If you don't want to spill your coffee again, you should walk more slowly than the way you walk naturally, or walk really awkwardly. Then, there would be no more crying about spilled coffee.
The only other option I can see here is to start drinking coffee from a much larger mug – one that isn’t “everyday” size. Hmmm… let me think about this…ヽ(ﾟ∇ﾟ(ﾟ∇ﾟ(ﾟ∇ﾟo(ﾟ∇ﾟ)oﾟ∇ﾟ)ﾟ∇ﾟ)ﾟ∇ﾟ)ﾉ
