the air is there because the cans are flexible, and most people put pressure on the sides to open them. If there was no air then soda would spill out easily. It also allows the soda companies to put slightly less liquid thanis actually stated on the can.

Most drink cans (especially soda cans) are made out of aluminum. They've very light and easy to manipulate and easy to reuse and recycle (helping to offset the high cost of extracting them out of the ground).
Cans were opened with a hammer and chisel before the advent of can openers. The tin cannister, or can, was invented in 1810 by a Londoner, Peter Durand.I think the first food packaged in a sealed metal can was from the 1820s or 1830s.The "can opener" was not invented until more than 10 years later. For those first ten years or so, people were expected to cut into the can with a knife or some other tool they already owned.
Only the ones that have a refund listed on the top can be returned. The rest have to be recycled so that we can be "green" with our trash. Any store will take them back. If the return machine doesn't accept them, and they have a deposit listed on the top, take it to the service desk and you will recieve the rebate there.

Yes it will. The aerodynamics will be affected and will make the Jeep less aerodynamic, thus reducing fuel economy. With the soft op on, air follows the shape of the top and slips by smoothly. Without the top, air hits everything in the inside of the Jeep which increases drag.

The fizz is caused by the carbon dioxide gas dissolved under great pressure into the soft drink. Opening the top releases the pressure and the gas begins to escape in a mass of bubbles.
