I found this one surfing the web for cheap led... ahah but.. For today.. it works!!! :D
Make a cup of coffee. You can add cream and sugar since it makes the bubbles easier to see but black coffee is fine. Hot tea or hot cocoa will work too.
Step 1 (the only step.. ): Watch the bubble.
When you pour the coffee into your cup, watch the bubbles.
If the bubbles move to the edge of the cup rather quickly, that's a good sign. Expect clear skies for the next 12 hours.
If the bubbles hang around in the center of the cup, get out your rain gear. You can expect rain in 12 hours.
If the bubbles slowly move to the edge of the cup, you may get a bit of weather, but it should be clearing in a few hours.
If you've managed to make a cup without bubbles, flop a spoonful of coffee back into your cup and make some more bubbles.
