At its coolest - or at least more YouTube-able - science is pretty much magic.
That's the case with Nitinol Wire, a material which is able to totally untangle and untie itself when placed in hot water, no matter how tightly you wrap it up.
Gizmodo points us to this brilliant demonstration, in which lots of wire is shown springing back into shape lots of times, and which somehow sustained our attention right until the end.
