It was exciting when we set up the 3-metre advertising pillar in the middle of Berlin Central Station. According to the main station, this area is frequented by over 300,000 travellers every day - we were curious to see the reactions. Many passers-by were simply in a hurry and wanted to get from A to B quickly - but interestingly, they were happy to take one of our little cards. And quite a few stopped: They asked questions, gathered information and got talking to us.

Our realisation: far too little is known about what you can do with tyres!
