Why does spiderman stick to walls when he has a suit between his fingers and the wall?

Answer 1

I think everyone is close to the answer, but basically the fine hairs (as depicted in the movie) are piercing through the suit and touching the wall. Basically, those hairs increase exponentially the surface area of his body touching the wall. There is a weak attraction (called the Van der Waal force) between molecules, and by increasing the number of contact points this force allows creatures to run up walls and stick to ceilings. A normal spider has about 600,000 points of contact with a flat surface and all those weak points of contact work to create one very strong attraction and allow a spider (or, in this case, Spider-Man) to walk up walls without a second thought.

Answer 2

His suit is extremely pourous - lots of micro holes. Spiderman has the same type of minitiaure hooks that are present with arachnids allowing them to cling to surfaces (wish I had them - imagine that!!) and do all of those things like walk on cielings - which are littered with loads of micro holes and crags that the hooks can catch. So when he jumps at a wall or cieling those little hooks do the same thing and cling to all of the imperfections of the surface (even seemingly totally falt surfaces - like windows - have imperfections). Since there are millions of these little hooks on his fingers and feet - his weight is easily suspended. There are theories that his actual body weight has been changed drastically due to the genetic mutation - so he may actually be extremely light - which also explains his ability to do many acrobatic things that may normally be carried out by someone who is physically much lighter....

Answer 3

I call it the suspension of disbelief. There are so many things you take at face value with Superheroes... things that would not work in the real world, such as unsable molecules, rubty quartz and all that fun stuff. When these heroes were designed, they never took physics or science in general into account, so there's a lot of retconning, like the "hairs" that many iof the posters here mention. The fact that a radioactive spider bit him would have killed him if the venom was radioactive is something that was never really taken into account...and most spiders do not have the abbility to pass on their abilities with a bite. :-)

Answer 4

Despite the fact that his suit is between his fingers and the wall, Spider-Man sticks to walls because his beautiful suit is made of special material that allows him to cling to walls as well as webs.

Answer 5

If one were to look at Spidey's skin under a microscope, his hair on his skin has been mutated to be like a spider-imagine tarantula or black widow. All sticking right up, I suspect they penetrate through his suit and that's what helps Spidey to stick to walls.

Actually, this was shown on the first movie itself, when Peter first discovered his new found abilities-you know, in the alley, when he climbed up some walls.

Answer 6

The World-wide Web.

Answer 7

his spikes come out of the special suit which cling to the walls

Answer 8

The suit is sticky like a spiderweb.
