Why don't spiders stick to their own webs

Why don't spiders stick to their own webs?
Why spider dont stick to their web
I took paper plates, made a web with a marker and then added tape all over it.
The kids touched how sticky the web was. Afterwards we discussed why spider don't stick to their own webs.

Why dont spiders stick to their own webs
The kids took turn walking their spider fingers cautiously around the web so they didn't get stuck to their own trap.
Answer to why spiders:
I Googled it and I found that spiders make a web and leave a trail of sticky glue droplets. They are then able to navigate cautiously around their web. At times spiders may encounter a sticky droplet, but are able to quickly lick it right off. Insects on the other hand don't have this privilege. Most insects fly, or hop right into tons of glue droplets making it impossible for them to escape. Resulting to them getting stuck in a sticky situation.
The magic School Bus has an awesome 20min video clip called The Magic School Bus Spins a web. It shows the spider make a web and then leave sticky glue droplets as the spider get ready to catch its lunch. I will post the clip for easy access.
