The silk is made up of protein molecules called spidroins, but their size and complexity makes them hard to work with.A group of scientists
Forced a solution of spidroin proteins through an opening in their behinds, pressure and an "acid bath" work together to bind the molecules together into a fiber.Copying this physical process as closely as possible, the team built their own web duct out of glass. This technique isn't ready for mass production or similar things but it's a starting point .
