Wrap a plastic sheet and seal it air tight to a jar and attach a small rod attach to the centre of the seal and allow it to pivot around the side if the jar could be a simple homemade barometer. Another model of barometer can be made using a sealed can attach to the tube inverted over a basin of water.
Some trouble on these type of barometer is the pressurized and depressurised could be affected by the temperature but at the same temperature, the effect of movement will be solely on the atmospheric pressure. An inverted glass tube filled with Mercury with vacuum space would be the best since the temperature would minimally affect but that would need large amount of mercury which is not readily accessible for a home experiment.
anaeriod barometer and a mercury barometer
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.

Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
