Put a piece of plastic film into hot water, and in no time it becomes a “crane”! This is not some kind of magic but a great scientific research. Scientists of Zhejiang University said that they have made a kind of new material which has “memory”, and the reason it can transform is because that the memory of a certain form has already been planted into the plastic material. The scientists believe that this high-tech technique can be applied to medical treatments and operations, and brings hope to the future design of heart supporting devices.
