British scientists have developed stretchable and strong artificial spider silk, made almost entirely of water. The artificial silk may be used to make eco-friendly textiles and sensors. The fibres are spun from a soupy material called hydrogel, which is 98 per cent water and the rest made of silica and cellulose.<br/><br/>It can absorb large amounts of energy, are sustainable, non-toxic, said the researchers of Cambridge University. The strength of the fibre exceeds that of other synthetic fibres, artificial silk and even human or animal hair.
