When your recipe calls for Barbados rum, reach for one of these: 1  Planation Grande Reserve 5 year. 2  Mount Gay Eclipse. 3  Doorly's XO.  R.L. Seale 10 year.
How To: 1  1. Purchase a hygrometer. One of the easiest ways to test your homeâs humidity level is to head to the drugstore and purchase a hygrometer or indoor humidity monitor. 2  2. Check for signs. If you donât want to spring for a store-bought device, there are several telltale signs of humidity.
How about relative humidity? At 3 p.m. the air has 9 grams of water vapor per cubic meter of air. We divide 9 by 30 and multiply by 100 to get a relative humidity of 30%. In other words, the air actually has 30% of the water vapor it could hold at its current temperature. First, the warmer air is, the more water vapor it can hold.. 2  Dew point is a measure of how much water vapor is actually in the air. 3  Relative humidity is a measure of the amount of water in the air compared with the amount of water the air can hold at the temperature it happens to be when you measure it.
