This week, I learn that it is possible to filter toilet water into clean water with no bacteria. Last week, we had Science Fair and there are lots of experiment that people do. Albert, Edward and Patricia  do an experiment on filtering dirty water into clean water. It was interesting and fun to learn. They made their own filtering machine and be able to clean most of the bacteria from the water. They evaporate the water and let it condense in different layer. This enable them to separate the dirty substance with water. They said it took them a few hours to filter it and it is very dirty to touch the toilet water. I think I can do this experiment in the future
