Our project is making a piece of equipment that we are going to use when we are stuck on deserted island with only dirty water. We decided on a project that includes a bamboo and a sports dink bottle. In the bamboo, I (myself) drilled 9 holes at the bottom and covered a piece of cloth. Then, I filled the bamboo with cotton, stones and sand (from bottom to top). Then, me and the team duct tape with what the made: a sports drink bottle 1/5 filled with stone, at the bottom of it, was a piece cloth held by a rubber band.
