A weather glass barometer is more of a do-it-yourself project as it requires only basic materials that we can usually find around the house. If you are constructing one of these during a spell of bad weather, you will have to wait until the weather improves to see how the barometer acts. Rising atmospheric pressure as a high moves in will press with more force on the surface of the water and push the column of water in the bottle to a higher level.
The only materials you'll need to build a weather glass barometer are: a clear glass jar (about 18 ounces), a clear straight-neck bottle (about 12 ounces), food colorant (whatever color you like, doesn't really matter), a rubber band.

Get a bottle with a straight-neck and a jar that is tall enough for the bottle to sit in upside down without having the neck touch the jar's bottom. Also, the bottle must not fit so tightly as to form an air-tight seal - so take that into consideration when picking out the bottle and jar.

STEP 2:
Fill the jar with enough water to come up just over the mouth of the bottle by an inch or a little more. Add a few drops of food coloring - useful only for visual glamour. Tip the bottle and jar enough to let a little air escape from the bottle so that the liquid ...
