Toilets are not only smelly, but also very interesting! From this investigation, we have learnt a lot about toilets! Many people have sat on the toilets, but have they ever thought of how toilets work? I bet a lot of them don't know!

We are very happy to do this project. In the 'History of Toilets', we saw that people were very clever to invent and improve the toilets. Also in 'Interesting Toilets', all the funny varieties of toilets showed us that people were really creative. All these toilets are designed to suit different people, rich and poor, and even for twins. 'Everything is possible!', we would say. Last but not least, the 'Mechanism' part told us how toilets work. Using a toilets is easy, but knowing how it works is more interesting!

Next time when you go to a washroom, think of the wonderful toilet and you'll smile!
