Producing spider silk is a biological feat‎

"Spider-Man: Brand New Day" turns organic web production into a superpower. In the 2026 film, Tom Holland's character, Peter Parker, begins producing webbing inside his body and shooting it from his wrists, rather than firing synthetic web fluid from the wrist-mounted mechanical web-shooters he used in earlier films. The switch transforms a familiar superhero technology into a biological ability and highlights the spectacular properties of real spider silk.
