Because chemistry and physics are magic, this is a video of a guy wowing his friend with a length of stretched out nickel-titanium wire (aka Nitinol, a shape-memory alloy) that, when heated in a glass of hot water above its transition temperature (the temperature at which it was deformed), returns to its original coiled shape. How about that! He then asks if the show of magic makes his friend want to kiss him, but his friend is too bewitched to reply. *shrug* All friendships are different. Still, shape-memory alloys — are you thinking what I’m thinking? “Transformer sex dolls!” Okaaaay, no you are not.
