I have an idea for how to create a rope and attach it to a wall/object using liquid. My concept is that it shoots two different chemicals out of 2 nozzles spinning together, and shortly after the chemicals leave the nozzle they widen and collide, creating a chemical reaction that becomes an extremely sticky substance and solidifies within around a second or two, if not less. My only issue is finding out what two chemicals would cause that kind of reaction upon collision. The result would be a device that essentially works as a Spider-Man Web shooter.
