Sixt: “Sun in Halle” [03:15]# Car rental firm Sixt Rent a car has launched a campaign to bring some sunshine to Halle an der Saale, which is said to be the rainiest city in Germany. To this end, they have hired pilot lieutenant colonel Sandro Wolf to break up clouds by injecting them with silver iodide. This gives local inhabitants the sunniest summer they have had in a long time, which, naturally, they enjoy to the full by going for long trips in convertibles rented from – you guessed it! – Sixt.
