I had a physics teacher who once told me that there is actually more than one way to determine the height of a building by using a barometer . . .
Method #1. Go to the top of the building, drop the barometer off the roof and count how many seconds it takes for it to hit the ground. Use the acceleration of gravity to calculate the height of the building.
Method #2. Measure the length of the baromter, then climb up the side of the building as you use the baromter as a measuring stick.
Method #3. While on the ground, tie a string to the barometer and swing it around your head while counting the number of revolutions per minute, then go to the roof with it and do the same thing. The difference in the number of revolutions will indicate the change in air pressure and will enable you to calculate the height of the building.
Method #4. Stand a distance away from the building, close one eye and hold the barometer vertically so that it looks like you are holding it along the side of the building. Using a red crayon, mark on the barometer where the top of the building appears to be. Now, while keeping the bottom tip of the barometer at the base of the building, rotate the barometer--in a direction away from the building--to a horizontal position. Make a note of what part of the ground the red crayon mark seems to touch. Then go and measure the distance from that part of the ground to the base of the building.
Method #5. Go to the owner of the building and say, "I'll give you this barometer if you tell me how tall your building is."
My favorite is #5.
Any other ideas?
