Berlin’s scorching summer is breaking records. Earlier this week the city experienced its hottest night ever, with a minimum of 25°C. The city’s trees are suffering, and residents are being asked to go out and water them. U-Bahns are getting noisier, as there's no moisture to lubricate between the metal wheels and tracks. The drains are stinking, so the water authority is putting “drain deodorant” down the pipes. The pools are all at capacity. But Berlin has only 48 public drinking fountains to help citizens rehydrate. A Berlin man who tried to become a police officer had his application rejected because he failed a drug test. A blood sample showed he had THC in his system. Undeterred, he took the matter to court, unsurprisingly rejected his case. The S-Bahn is trialling automatic doors to improve punctuality. All doors will pop open at stations between Ostkreuz and Hauptbahnhof from 6am to 8am. Instead of 24 people pushing 24 buttons, one person pushes one button. Why haven’t they ever done this before? This month the new home sharing regulations come into effect in Berlin. You’re now allowed to rent out up to 49% of your flat online, but first you have to get a registration number from the Bürgeramt and display it on the various rental portals. Just a week to go until the Mobile Kino Summer Camp - the Lakeside Film Festival in the woods. It’s three nights of movies and music under the stars out in Brandenburg. We’ll be there recording a live episode of Radio Spaetkauf.
