Pneumatic tube

Pneumatic tubes or capsule pipelines are systems of air-driven containers in a network of tubes used for transporting physical objects.

Pneumatics can be traced back to Hero of Alexandria in the 1st century AD. The Victroians used capsule pipelines to transmit telegraph messages, or telegrams, to nearby buildings from telegraph stations.
