The pneumatic tube system works by using air pressure to transport cylindrical containers, or carriers, through a network of tubes. When an item is placed in a carrier and the carrier is loaded into the tube, air pressure is used to propel the carrier through the tube to its destination. The carrier is then removed from the tube and the item inside is retrieved. This system is commonly used in hospitals and other facilities to quickly transport items such as lab samples, medications, and paperwork between different locations. **
