Lifestyle No chewing gum on ground October 24, 2013 Photo courtesy of the City of KaiserslauternA machine for used chewing gum can be found next to the Stiftskirche in the center of Kaiserslautern until mid-November. Citizens are asked to dispose of their gum in the machine and not spit it on the ground, where they stick and become difficult to dispose of. The machines for used chewing gum keep the city from having to use expensive lasers to clean the streets. This idea was highlighted during a scientific idea contest. Six ideas were chosen and worked by scientists in research groups and institutes. Two more machines are set up at the corner of Schneider-and Marktstrasse and on Fackelstrasse 38. « Previous × Next » Share Tweet
