I've notice for some time now that when I leave bread inside a plastic bag above the fridge, after a day of two, the water or humidity inside the bag or the bread starts to acumulate below the bread, to a point that you can actualy see water droplets, while other parts of the bread are completely dry and hard. Note that the bread is OUTSIDE the fridge, not inside, and most of the times the bags were tightly closed.

This certanly doesn't happen if I leave the bread anywhere else, so it must be an effect of the fridge. Could it be some kind of magnetic effect that makes the water molecules try to "stick" to the fridge, and thus they acumulate bellow the bread (where is closest to the fridge)? Or does it have something to do with the vibrations of the fridge?

Also, I leave a box with medicines above the fridge? Is it safe? Or the same effect could adversely affect them?

Cheers!

Has anybody done studies or ran simulations that factor in the increase in Humidity due to a city full of Hyrdogen powered vehicles? What effect would this have on weather patterns? and what health problems could arise from the obvious massive increase in moisture in the air?

It must something to do with humidity, but why?

I have been told that the wind has more force on a yacht's sail in conditions of high humidity, such as in the tropics, because the higher water content of the air increases its mass, and therefore the force, on the sail at any given wind speed.

Is this true? If so, is there an equation I can use to calculate the increased force?
