Every time I watch Avengers: Infinity War, I can't figure out how Spider-man is able to swing in an open area. Is it a mistake in the movie? Please watch the Ebony-Cull invasion scene following:
Let me support this using pics:
Here, he uses SOME support after jumping ahead of the bridge, note that the nearest trees/buildings are quite away and he is swinging away from the bridge, so the web is not on the bridge railing.
Here the web support's height is far more than any tree possible in the surroundings, the web seems to have no logical support.
Notice there are trees in the corners of the road only, too small trees compared to the very long length of the web(s).
I see that his webs have no logical support whatsoever.
