What happened to the cup?
Students investigate why some plastic cups collapse when filled with hot water and some don't. They compare the effect of hot water on a range of cups and relate their findings to the properties of the plasticsused for each cup: whether it is biodegradable or not, its melting point (Tm) and its glass transition temperature (Tg).
