I have been told about the transparent toilet long time ago. Not have a chance to use it and even not know how is that working. Most time I saw on the internet is a see-through toilet on the street, like this:
I swear I won’t take a try until I know how it works (em… maybe not even after I know.) But, anyway, spent sometime search on the company who invented it, I got some brief idea of it… just shared with you guys so when you actually see this transparent monster on the street, and you really need to use it. There is no need worrying about the transparency.
