Every day tons of rubbish is made in the world. Some are degradable but other things especially plastic does not degrade and this is polluting the environment every second. -The concept of Reuse, Reduce and Recycle is there but not people all over the world use it. So, coca-cola has came up with a very clever way to promote it’s product and at the same time encourage people to reuse coca-cola bottles. A Coca-cola advertisement has been uploaded on YouTube and it is a very clever ad. In the ad some kids go to a shop and buy some coca-cola but at the same time the shop keeper also giver them something. And later the kids make a water gun from the coca-cola bottle. Similarly, the same coca-cola bottle is used to make markers. Ink is filled in the bottle and a tip is added through a small hole in the bottle cap and kids can be seen drawing with the help of the coca-cola bottle. There are other many things that are made with the coca-cola bottle. A man changes it into a spray bottle, some turn it into a ketchup holder, some change it into salt shaker. At the end a small light source is added to the cap and the bottle is made fun.
