Metals always have germicidal and antibacterial properties against polluting drinking water and this idea was utilized in the project “Save Water”. This innovative concept utilizes a glass bottle for water stock and a small metal body inside with the note ‘Save Water’. This will allow users to always be aware of efficient use of water and save the planet as well. When the bottle is filled above the inner article level, the Save Water note will be seen bigger than its original size because of the water. When the water level goes down the insider part, the note becomes easier to read, and finally the process of oxidation will darken the words slowly and emphasize the message more each day : Save Water !
