Physics is cool you see

Spidöh Man here has weight
The web meanwhile has elastic energy

So, you need to show how much effort it take for the web to lift him up. As he’s preparing to spindle his other weeb, show his body move up and slow down as it rises (vertically slowing, not horizontally) and behind to fall till he indeed spinds.
So, when he ejactulates the second web, have his body be yanked up, his arm straight up and completely straight as his body drops a bit before being tugged with the webble. This is because Spinge Man weighs heavier than a loaf of bread and so he’s got some decent weight still pulling down. This is also due to the sudden force pulling up against his weight and gravity pulling down.

There, advice.
Nice.
