How can I make a Nerf Pocket Vortex?

Since the completion of my 2 inch piston valve pneumatic rocket launcher Ive been looking for a cheap source of pocket vortexes. I cant find any under 3 bucks. Does any one know of a cheap way to make similiar projectiles, thanks? I was thinking of making a mold and filling it with great stuff, then tossing BBs or pennies in for weight.

try and go here there nice and cheap

In my experience, Great Stuff doesn't like to cure inside enclosed molds, but I think casting the missiles is a good idea. Maybe check at Smooth-On for an A/B flexible urethane foam that would approximate Nerf density?

That looks like good stuff, but at that price it would almost be cheaper to buy the vortexes, I was thinking of makeing one out of pipe insulator, Add a weight in the front and a tail to the back
When you consider the expansion factor, it's actually not that bad pricewise. You could probably make a perfectly good missile-like object out of pipe insulation, though. I thought you were going for the Vortex look, but if that's not a huge factor, the insulation would definitely work.

 Im going more for performance that asthetics, the plan is to get a piece of insulation that fit into the barrel and slide smaller piece into that till a piece of foambacker rad can fit in for a tail, a piece of wire will be in the backer rod, fins will be cut from a foam sheet, I will put some weight at the tip and use easter eggs for the nose, Ill make an instructable if it works. 
Sounds cool. I look forward to seeing it.

You could check to see if your local dollar-store has any nerf type balls.
They might have something similar, other than that, I could only suggest checking for a gross shipment of them on ebay.
