You're walking along the street. You need to go to the washroom desss ...perately. What do you do? If you can't control yourself, you could be embarrassed to no end .
Don't worry. Someone in San Francisco has invent ed a self-cleaning public toilet . The toilet cleans itself. The seat goes back into the wall where it is washed and blow-dried. Even the floors are washed automatically . You must be quick, though. You've only got 20 minutes to "do your business." Then, there's a 2-minute warning before the door opens.When it does, you'd better be ready or your face will be red!
