nah i don't think that can work but you can try. I really agree with Kuriatey. If we can use the chemical to make the nylon but add some very stocky compound to it that bonds. Also as it comes into contact with air and it stretches and pulls.
I'm probably the newest person here so if you will, please go easy on me. That being said, nylon (specifically Nylon 6,10) is the best idea so far. Remember this though, all substances have different properties.
The type of nylon created there has four problems:
1.) It isn't fully reactive. This means it might still react with CO2 giving it unwanted properties.
2.)It isn't highly elastic or biodegradable.
3.) The polymer created is a thread and not a rope.
4.) It is flipping expensive.
That being said, it has various advantages.
1.) It is probably the easiest to make
2.)It has properties similar to web such as tensile strength and elongation

3.)It is reactive allowing for minor tweeks to the formula.
4.) It is created instantly
So with all that concluded, The main issue is the adhesive that is applied to the polymer. I recommend the pressure activated adhesive found in duct tape. The reason why is that dragline web such as the kind spiders use for webs have a glue that will increase strength due to the struggle of prey.
The design for this webshooter would depend on the type of glue used for the adhesive properties. Nanoglue and gorilla glue sound the best to me.
It would involve about six holes with one larger than the rest which the nylon would come through. now as for the designed chambers, that will depend on the glue. We don't want it to react with the hexamethylenediamine or the sebacoyl chloride. I will continue tweeking the formula if you guys want.
Also: Silly string won't contain any of the properties no matter how much you reinforce them. Sure it has the spontaneous polymerization with the yards of string that seem to defy the amount of fluid in the can but the reason why is that it is foam. Foam. Unless you want to risk the tensile strength on shaving cream, it won't work. Only the fiber synthesis will work for this scenerio.
