Cow dung air freshener was apparently created by two teenage girls in Indonesia as part of a science fair. They won the gold prize.
Two Indonesian high school students have made an air freshener out of fermented cow dung and said it doesn’t smell anything like what one might expect.
Dwi Nailul Izzah and Rintya Aprianti Miki came up with the air freshener at the Indonesian Science Project Olympiad. They won a gold medal at the event for their creation.
They claimed to have sourced their ingredients from a cattle farm before allowing it to ferment for three days. They then took the water from the mixture and blended it with coconut water before distilling it of impurities.
Judges commented that the air freshener, which is free of synthetic chemicals, had an herbal-tinged fragrance.
The report also said it is also a lot more affordable to make. Normal air freshener can cost as much as $4 for a standard can, but the natural variety will cost around $2.
Rocket News 24, which also cited the Arduino, said the two teenagers are going to file for a patent of their product.
