How does a spider spin web from one corner to another in the mid air room?

Spiders do not spin webs from one corner to another in mid-air rooms. Spiders typically build their webs in areas where there is support, such as between branches of trees or in corners of rooms. They use their silk to create a framework for their webs, and then add sticky droplets of silk to catch prey.

If a spider were to spin a web from one corner to another in a mid-air room, the web would not have any support and would likely collapse. Spiders are not able to control the direction of their silk, so they cannot create a web in mid-air.
