We were asked by Keep Britain Tidy to make giant models of cigarette butts to place into a tank at Sea Life Manchester for a photo shoot to launch their latest campaign #BinTheButt to stamp out cigarette litter, which causes significant damage to marine life. There were a few challenges to this project; we had to be sure that what we created didn’t poison the marine life in the tanks and also that the cigarette butts we made were heavy enough to stay at the bottom of the aquarium and not float away, so we weighted them by filling them with stones used to decorate aquariums as this isn’t dangerous to marine life.
