So Spider-Man shoots a web from his web-shooter thingy, grabs on to it and swings through the air, at which point he shoots another web from his other web-shooter thingy and repeats the process.
How does Spider-Man's web become detached from the web shooter thingy? He certainly doesn't seem to be yanking it free. Does he have little tiny fingernail clippers inside that chop it off after each web is shot?
EXPLAIN THIS TO ME.
UPDATE (30 SECONDS AFTER I WROTE THE PREVIOUS SENTENCES, WHICH WAS AROUND THE SAME TIME I DECIDED TO CONSULT WIKIPEDIA):
Pressing down on the palm-trigger of the web-shooter causes the valve in the nozzle to open wider, expelling the fluid. Releasing the trigger causes the valves to close, cutting off the web-line or fluid. If Spider-Man creates any variation to his normal web formula that is too strong for the pinch valves to sever, he might end up being tangled up or tied to the object he attached his web to, which has happened on more than one occasion. His web-shooters require constant maintenance and on more than one occasion suffer jams or malfunctions.
Soooo... you know. Never mind.
