Why Pneumatic TraveI Is Not a Thing Anymore

Ever heard of pneumatic tube transport? It's this crazy system that was like the OG version of instant messaging, but with actual physical objects. Back in the 19th and 20th centuries, people were sending all sorts of things through these tubes – from mail to cats! Yeah, you heard me right, someone actually sent a cat through the tube in 1897. Then there's the prairie dog vacuum from 1996 – talk about bizarre! And hold onto your hats for the Whooshh system, complete with a fish cannon to help salmon get over dams. I mean, who even comes up with this stuff?
