A UCL-led research team has created the world's thinnest spaghetti, about 200 times thinner than human hair. The spaghetti, just 372 nanometres thick, was made using the 'electrospinning' technique in which threads of flour and liquid are pulled through the tip of a needle by an electric charge. At 372 nanometres, this spaghetti is narrower than some wavelengths of light.
