Winnie: Mary, look at the toilet. It’s so special!
Mary: What’s so special about the toilet?
Winnie: There is no water but just mud in the toilet!
Mary: Wow, that’s special. Is it stinky?
Winnie: Not really.
Mary: Here it says, “A Bio-toilet.” What’s a “Bio-toilet?”
Winnie: Let’s look it up on my smartphone. It says, “A Bio-toilet is a dry toilet. It needs no water. People can use this kindof toilet in places with no water.”
Mary: Then, how does a Bio-toilet work?
Winnie: The key is the bacteria in the toilet. The bacteria decompose people waste and the toilet is not stinky!
Mary: It’s great!
