Crushing bottles


Following crushing some cans with a vacuum, the students were curious to observe the process in action again. Therefore, we crushed an empty fizzy drinks bottle and measured the pressure with the @Pascoscientific pressure sensor. The pressure dropped inside the bottle to almost zero Pascals ( the unit of pressure measurement). A vacuum pump or hand-held vacuum device can be used to remove air from a bottle. The bottle is connected to the vacuum pump or device with a tube, and the air is then pumped out of the bottle, creating a low-pressure environment. As a result, the air pressure inside the bottle decreases, which can cause the bottle to collapse or deform if it is not strong enough to withstand the external air pressure. This process can be used for various purposes, such as preserving food or creating a vacuum-sealed environment for experiments.
