🛼Exploring sunrise Bremen (Germany) by inline skates

My buddy and I visited Bremen (Germany), a city of the Hanseatic league. This day, I left for inline skating trip at 5.45 AM. At this unique time, the city was empty and I was all by myself. I visited the campus of Bremen University. I recorded a tower on the campus but did not think much of it at the time. It later turned out that tower was the place where the lowest artificial temperature ever was created: a whopping -273.15 °C. WOW! Legendary science. I explored the empty campus and moved on to a large car plant in Germany. I was done by the time the city was waking up.
