Methodology The materials needed for our experiment are six plastic cups, six cubes of meat, couple of rubber bands, mesh cloth, pair of scissors, tape and folder. The sic plastic cups are separated one by one. The first pair is just an open container. The second one is covered with mesh-cloth and the last pair is covered with folder. Each meat is placed individually inside the plastic cup. The first pair will just be set aside because it doesn’t need any preparation except for the meat itself. The second pair set-up will be covered with mesh-cloth. We put two layers of mesh-cloth and used rubber bands to fix its position on top of the plastic cup. Lastly, the set-up of third pair will be covered with folder. We cut the folder slightly matching to the size of the lid of the cup then sealed it with a tape. Reference: None
