Scientists: The answer to string 'spontaneously' knotting

Scientists have shown that cable roughly the length of a set of headphones cannot help but tangle itself into a knot.

Experiments carried out by school pupils in Coventry, proved that the longer the length of a piece of string, the more likely it was to form a knot, if jangled at random.

But Robert Matthews, a physicist at Aston University, Birmingham, has come up with a solution after formally testing the theory with the help of pupils from Coundon Court school, near Coventry, who carried out 12,000 tests.

"Simply clipping together the two ends of the cords makes the cable less likely to form a knot, saving the frustration of having to untangle it before plugging in," he told The Times.
