This may look like an ordinary paperclip, but its reshaping property is going to surprise you!
Twist it, turn it, bend it or even mould it – this paperclip is going to get back into its original shape. It is made up of Nitinol, which is also known as nickel-titanium or Shape Memory Metal (SMA). When it comes to Shape Memory Metals, they can be deformed at a particular temperature and then restored into their original shapes in another one. In this video, the paperclip is molded easily in room temperature but gets back to its original shape in hot water.
