Who would think about making air freshener using cow manure? The answer is two high school students from Indonesia.Dwi Nailul Izzah and Rintya Aprianti Miki won first prize in the country's Science Project Olympiad with their alternative and environmentally-friendly air freshener.The air freshener is said to have a natural fragrance of herbs and is good for human health because it doesn't contain any harmful chemicals like other fresheners on the market.
The girls collected cow dung from a cattle farm in Lamongan regency of East Java and left it to ferment for three days. They then extracted water from the cow dung and mixed it with coconut water. The liquid was distilled to remove any impurities and the end product is a liquid air freshener with a natural aroma of herbs from digested cow food.
