Air Freshener Made From…Cow Poop? [VIDEO]
I don’t know about you, but when I think about an air freshener, I think about a pine tree. Cow manure would probably be last on the list of things that I would use. But that’s the base ingredient in a new air freshener created by two Indonesian students.
The invention was for a science project, but it seems to be working for them. It’s said to have a natural fragrance of herbs and is good for human health because it doesn't contain any harmful chemicals like other freshener products on the market.
