USEFUL RECYCLED ITEMS? Our science teacher told us to make something out of recycled objects. For example: Bottles, straw and balloons would make a Lung Model. But my classmate already has a Lung Model, so I want something unique and useful. Please give examples, express your ideas.
can you also make some recycle.... that can use an stiro cup and anything that can make an dayograma disign... or make some think if what you want to do..
