Rather than transporting fluids, pneumatic tubes are usually used to transport solids in a cylindrical container by compressed air or by partial vacuum. They were most popular in the late 19th and early 20th centuries, and were used to transport small solid objects within a building, e.g. documents in an office or money in a bank. By the 21st century, pneumatic tube transport had been mostly superseded by digital solutions for transporting information, but is still used in cases where convenience and speed in a local environment are important. Hospitals, for example, use them to deliver drugs and specimens.<ref>{{Cite web |last=Wykes |first=Sara |date=2010-01-11 |title=Gone with the wind: Tubes are whisking samples across hospital |url=https://med.stanford.edu/news/all-news/2010/01/gone-with-the-wind-tubes-are-whisking-samples-across-hospital.html |access-date=2024-12-09 |website=[[Stanford University School of Medicine]] |language=en-US}}</ref>
