KNOW WEATHER BY COFFEE OR TEA !

PROF WAQAR HUSSAIN 

    

         One can predict weather by coffee cup or tea cup. Prepare a cup of coffee or tea. In it, you can add milk and sugar as milk enhances the visibility of bubbles. Now, observe the movement of bubbles.                                                

1)   If they 

move quickly to corner, it indicates clear weather and there is no chance of rain in next 10 

hours or so.

         2) If, bubble hang around in the centre then there is chance of rain in next 10 hours or so.

     3)    If, bubbles slowly move towards the edges of the cup, it shows cloudy weather.

      The science behind the trick is that high pressure causes the bubbles to move to the edges and high pressure of atmosphere result in sunny, clear weather and low pressure doesn't move the bubbles and low pressure system often result in rain. The slow movement of bubbles towards edges indicates partially low pressure and thus weather is partly cloudy and partly sunny.
