Design an experiment to test the air pressure at different altitudes?

The historical experiment is to create a long, thin glass tube, sealed at one end. Immerse the tube in liquid Mercury then stand it upright so that there is an evacuated segment at the top (sealed) end of the glass tube. Then walk up a mountain and not how the height of the mercury in the tube changes. Warning: Mercury is poisonous, deadly so after long exposure.

What pushes Mercury up in a tube of a Mercury barometer?

That depends on the 'tube' involved. In a thermometer the mercury expands and contracts within a sealed tube as the temperature is raised or lowered. In a barometer there is a reservoir of mercury which the atmosphere presses on. This maintains the mercury in a column which is sealed at the top. Increases in atmospheric pressure push the mercury further up the tube, decreases let it drop down the tube.
