This time, the pneumatic track is roughly 70 meters long. It goes from the entrance hall, through the staircase into the first floor, where it passes the institute's library, then it makes its way back to the ground floor. The balls race through the entire pipe system within 11 seconds, which makes them in average 22.91 km/h fast (The video above is in slow motion). That's stunning to watch and fun to play with. Give it a visit when you're in Prague!
Participants are encouraged to put their golf ball into an entrance in the wall. After a few seconds of rattling, the ball becomes visible through an opening in the broken lathe, stuck inside the wall. The goal is to figure out how to get the ball out from behind the wall so it can be used to play the adjacent mini golf course.
A source of light seems to be moving inside, towards an opening in the bottom of the wall. Inside that opening, a small luminous being is visible, standing on piece of wood, slumped over and depleted.
Participants interact with the being by putting their arms through ceramic portholes in the wall, using their hands to first provide "energy" to the being and then to provide a physical platform for it to jump onto.
The latter is at Urban Putt. To those of you I actually know in real life: I haven't been to Urban Putt in a while and we should go.
