Filtering water in class

19 Nov

Some “relax” just before our first term exams. On Friday we have discovered how to filter dirty water in our class. It was a surprise to see how water was coming out of the filter… but not as clean as we thought.

Great solution from one of the students: we should filter the water several times to get clean water.
