Coffee and Weather

 Many of us wake up every morning and are completely dependent on coffee. Nothing happens until that first cup, and some people are just flat out grumps without it. For whatever the reason may be it’s part of our daily routines. Not too many of us are aware of this, but your cup of coffee tries to send you a message every morning that might help your day.

The legend is that while pouring a cup of coffee the day’s weather forecast can be seen in the bubbles that rise to the surface of your cup. If they stay grouped together in the middle, it should be a nice day. If they disperse to the edges of the cup, you can expect rain. This info comes from "Weather Forecasting" by Michael Hodgson from the "Basic Essentials Series".

You see the science behind it has to do with high and low pressures and how it effects the surface tension of the coffee. Fairly strongly brewed coffee works best (instant lacks the oils in it for the surface tension). After giving the coffee a couple stirs in a straight sided mug, bubbles will form and go to the sides of the mug if a low pressure system is present causing the surface of the coffee to form a concave shape thus pushing the bubbles to the side of the mug indicating a possibility of rain. If the bubbles scatter all over then collect in the center, a high pressure system is present indicating good weather which is due to the convex shape of the liquid.

I’m not saying this is fool proof and guaranteed to work, but I think predicting the weather is one of the only jobs that you can be wrong all the time and not get fired from. So, why not listen to your coffee, it’s probably just as accurate as your local meteorologist.
