Kind of like a popbottle rocket but pumped into a barrel and out comes the dart... but for popbottle rockets, I recall, they require water... Is there a good way to attatch a pump, to a bottle, to the gun without any air leaking and without using water to project the dart?

What? I don't really understand what the fuck you're talking about. At least show us a concept drawing.

Um, i'm guessing it would be no. You seriously make no sense.

I'm pretty sure he's talking about those air pressure rockets...the kind you fill partway with water, attach to a pump, and pressurize. When you release the retaining clip, the air pressure forces out the water, launching the rocket.

As far as using that kind of concept for nerf...well, that's pretty much the idea behind any air pressure gun. But there's probably no good way to pressurize the gun through the barrel, and then be able to remove it quickly enough to fire a dart.

Thats exactly what I am talking about... thank you Carbon- because my picture was crap! I have been thinking of how to do it and I have been getting stuck on how to keep the air from leaking... and how the trigger mechanism would work...

Intresting concept, but why wouldn't you build somthing like the BAMF instead? I'm pretty sure if you go through with this, it'll be almost the same as it.

This thread is pure concept. Let's just stick to what we know for now. Anyways, that sounds like trash to me; way to long to pump and it would shoot too hard. Um, and I couldn't really understand it either.

popbottle rocket= 2 liter bottle with fins and nose cone filled with water and pumped with a bike pump. It's one of those grade school like experiments. Am I the only person who thought those were cool when I was a kid? In any case, it would basically be an air powered homemade gun. Nothing new.

Oh, those things rock. Sometimes, i would just take a 20 once Coke, put the cap on very loosely, and jump on it. It went 40 feet, and dust kicked up. It was pretty cool. if you get it tight enough, you could just put some PVC on the bottle.

Forgotten hero (if anyone remembers him) built a ball-valve homemade using a 2-liter for the tank instead of PVC. It worked really well.

I remember that, didn't he also have a spring gun that used a can of pringles?

I think it was a push-plunger, like an NB-1.
