Engineering is important because it use creative thinking, and new ideas to solve the problems.

Our challenge was to find a solution for cleaning the water on a deserted island. We had to design a device that could perform.

We choose our design because it was not too hard to build and we thought the material is easy too find on the  island.

You put the water into the bottle and when the water comes out, you can put is in a clean bottle .

Our design was not successful, we know this because the water came out was not clean.

If I could change my apparatus, I would not make a hole in a plastic cup but insterd the clean water in it, and not the additional bottle. Finally I would add more layers of material into the filler so that the more water will come out more cleaner.
