Once it ’s swallowed up by a series of pneumatic tubes , the case shot embarks on a dismal , shadowy journey unobserved by the human eye . But now we have GoPros , and now we can see precisely what the interior of a pneumatic tube arrangement looks like .

It ’s soft to consider of pneumatic thermionic valve as a fussy old , system for push pieces of paper around . Before telephones and the internet made communicating instant , Paris , for example , had an entire secret postal system of rules that give up mail via compressed atmosphere across the city . But pneumatic tubes are becomingever more popular again , with complex system being installed in hospitals , savings bank , and supermarkets . This particular video was shot inside a parliamentary building in Norway .

Unless you mouth Norwegian , you might want to skip to takeoff at 1:10 , which feel almost like a mini rocket launch . Then it ’s off we go . The GoPro - eye persuasion is quite radically disorienting — since flying through thermionic tube is not something we humans usually do — but you ’ll see points where the canister slows down and quicken up . Pneumatic subway systems can be pretty complex beasts , where multiple case shot are routed to any phone number of issue points by computer - controlled airflow . Not so old - fashioned after all .
