Water filter project

– we tested the basic layer of the filter, and it turns out the water goes through perfectly.

-we added the other layers and stabled them.
-result: the dirt and rocks and all the stuff are filtered, but there is still some kind of yellowish things in the leftover filtered water. The problem is, the water always leaks
from the gaps of the tape.
– next time: maybe next time we can do better by not putting too many layers, so the mainly of the water doesn’t get absorbed by the fabric and stuff.
