A hacker conference (organized by the Chaos Computer Club I'd guess, a famous hacking club of many decades),
runs, during the conference (and surely just for fun)
their own "silk road" (a clandestine marketplace, named after the namesake "dark web" online marketplace, where people bought drugs and other illegal services)
on top of a pneumatic tube network - a network of connected physical pipes used to send messages pushing them using air (e.g. some paper note inside a container). Pneumatic tubes were a physical "instant messaging" system used in early 20th century offices and large organizational buildings.
This "for fun" pneumatic tube network is powered via regular vacuum cleaner motors (as opposed to the air pressure being produced by some dedicated motor).
In this network, inside the conference area, people send lots of BS spam messages for fun, and sometimes even vodca shots (inside some container) from one point to another.
People attending the conference can build their own tube capsule (their own message/small item container to be transmitted through the tubes), but they first have to show that they can run through a test track (a smaller test pneumatic pipe line), so that they don't stuck/create issues when they put them into the main network.
> "silk road" (a clandestine marketplace, named after the namesake "dark web" online marketplace...)
The dark web marketplace itself was jokingly named after the original "Silk Road", a "network of Eurasian trade routes active from the second century BCE until the mid-15th century.[2] Spanning over 6,400 kilometers (4,000 miles)" [1]
