Synthetic Webbing

"You know what I think is really cool? This webbing. Tensile strength is off the charts. Who manufactured that?" "I did."

- Tony Stark and Peter Parker

Synthetic Webbing is a substance developed by Peter Parker to help him in his role as Spider-Man. Made from chemicals that can be found in an average high school chemistry lab, it mimics the properties of the actual silk produced by spiders.

Creation
After being bitten by a spider and acquiring spider-like abilities, Peter Parker chose to fight crime in the streets of New York City as the masked superhero "Spider-Man". Using his knowledge of chemistry, Parker devised a formula to make this specialized substance, and using parts he acquired via dumpster diving, manufactured crude (but functional) Web-Shooters.

Recognized by Tony Stark
Around the time of the Avengers Civil War, Peter Parker returned home from school, greeting his Aunt May (without looking) before acknowledging the presence of Tony Stark, his biggest idol, in the living room, which caught him off-guard and left him speechless. He became confused when Stark told his aunt that Stark Industries planned to give him a sizable grant, claiming that Parker had signed up for it in the past. During a private conversation in Parker's room, Stark showed him footage of the rumored "Spider-Man" that was said to be active in New York City for several months. His videos showed a figure in red and blue clothing apprehending criminals and stopping speeding cars with his bare hands. Stark jokingly wondered if that figure was not Parker, to which Parker awkwardly denied the figure's existence, claiming all of the footage had been edited. Stark, however, quickly discovered the hiding place that housed the makeshift outfit that Parker used as his costume. Parker had no other choice than to confess that he had been Spider-Man for six months. Stark ridiculed Parker for his cheap costume, but was impressed by, and complimented, the tensile strength of his web fluid and asked who had made it.

Stark invited him to come to Germany to confront Captain America, but Parker claimed he had too much homework to join the mission. Stark, however, decided to ignore that comment before saying that the mission could be dangerous and decided to tell Aunt May that he was taking Peter out on a field trip. As Stark walked toward the door, Parker over-reacted for a moment and used his Web-Shooters to web Stark's hand onto the door knob, and sternly ordered him not to tell Aunt May. Stark relented before asking to be freed from his webbing.

Minor Upgrade
"Is this stuff coming out of you?"

Peter Parker was then escorted by Happy Hogan aboard Stark's private jet. While Hogan was driving him, Parker made a video throughout his trip which Hogan told him that he could not show it to anyone. When they arrived in Germany, Parker explored the country video-logging everything without actually knowing why he was there in the first place, having then been told to suit up to go onto the mission in just a few minutes, Parker then prepared for his upcoming fight with all of the rogue Avengers and put on his original suit and warmed himself up by filming himself in the mirror.

Hogan soon walked in on Parker and, bewildered, asked Parker why he was not wearing the suit that Tony Stark made him, only for him to question what Hogan meant as he had not yet found anything from Stark in the hotel for him. Parker, who was unaware of such a suit, then located the suitcase in another part of his hotel room and opened it, revealing a new Spider-Man Suit and its features and upgrades which had been designed for him by Stark Industries. Parker, speechless, put on the suit and joined Hogan who took him to Flughafen Leipzig-Halle airport, with Hogan showing no patience for Parker's excitement over his new suit.

Parker waited for his cue from Iron Man to join the fight, Peter secretly filmed the standoff from a distance, capturing Iron Man along with other members of the Avengers. Spider-Man swung into the standoff, stripping Captain America of his shield with his webbing while also binding his hands together, but quickly became distracted at the sight of the Avengers. However, Spider-Man was surprised by Ant-Man, who had managed to sneak onto the shield and kick him in order to return the shield to Captain America. As the Avengers began to fight each other, Spider-Man asked Iron Man what he was supposed to do. Stark told Spider-Man to keep his distance and use his Web-Shooters against Captain America and his companions.

Spider-Man then followed Falcon and The Winter Soldier into the airport terminal building. During a battle with Falcon, he webbed him to some hand railings in the terminal building but became distracted, this time by the EXO-7 Falcon, wondering if they were made from carbon fiber as he rambled about the sophistication of the harness, much to Falcon's irritation. Spider-Man was able to trap him and Falcon in his webbing, knocking them both onto the ground floor below. As he began to apologize for their fight, Peter was snatched away by Redwing, which grappled his leg and flew through a window, dropping him outside while Falcon and Winter Soldier escaped.

Captain America brought Spider-Man to the ground when he threw his shield at Spider-Man's webbing. The pair expressed their respect to each other while Rogers asked what Tony Stark had said about him, with Spider-Man explaining that Stark believed Rogers was wrong about his views on the Sokovia Accords and that made him dangerous. Spider-Man also explained that Stark had advised him to aim for his legs, which he did, using his Web-Shooters to trip Rogers and drag him across the ground while kicking him. Spider-Man attempted to subdue Rogers by webbing his arms and pulling him backward, but Rogers was able to flip out of the situation and throw Spider-Man away from him before hitting him hard across the face with his shield. Seeking to end the fight, Captain America used his shield to damage the support beams of a platform, which fell and forced Spider-Man to hold it up and retrieved his shield and prepared to rejoin the battle.

Realizing that he had to go and help his team fight against Giant-Man, Spider-Man placed his phone on the ground, and cursed in amazement at the sight of Scott Lang towering above them all. When War Machine was thrown across the airport by Giant-Man, he was about to smash into an aircraft parked just outside, but Spider-Man saved him by firing his own Web-Shooters at War Machine and then pulling him away from the aircraft and swinging him back.

Towards the end of the battle, Spider-Man, inspired by the movie , came up with a strategy to defeat Giant-Man. He webbed up his legs so that Giant-Man would lose his balance, and then let Iron Man and War Machine hit him against the helmet with full speed. As Giant-Man fell over, he inadvertently hit Parker, making him fly into a pile of wooden boxes; knocking him unconscious for a short while on the battlefield while the fight continued elsewhere on the battlefield.

Honing His Formula
As he kept a close watch on the time until the end of the school day, Peter Parker then went to Cobbwell's class in which he was being taught about quantum theory. However Parker instead focused on upgrading his web fluid for his Web-Shooters. As Parker mixed the chemicals together to create the fluid however, he discovered that it was forming much too fast and soon began to overflow over the glass he was using.

Capabilities

 * Durability: While examining Peter Parker's homemade Spider-Man Suit, Tony Stark expressed his amazement at how strong the synthetic webbing is, proclaiming the tensile strength to be "off the charts". Later, when interrogating a known criminal, Parker reveals that the webbing takes two hours to dissolve.
