Any ideas for a 1 1/2" union?

[noname]

I have a 1 1/2" union, Sch 80 (but white!), but I have no money to do stuff with it. I was thinking about a large all Sch 80 gun, but scrapped that idea because of the cost. Instead, I'm working on developing a new triggered burst disc system. But that's also delayed, due to money.
Any other ideas?
No, I'm not going to make another hybrid, although I do have some 1 1/2" Sch 80 pipe....

hook up a big chamber and no barrel for some noise making fun.

I can make enough noise already, by shooting a 1" union'ed gun. I was thinking about buying a 3" Sch 80 union (this thing was HUGE), but though against it, because it was almost $20.

20$?
Thats a good price for a union of that size.
most 4" sch 80 fittings cost me around that price

I know, I just had neither the cash nor pipe big enough for it on hand. The bigest size pipe I have lying around is 2 1/2" Sch 40. They had 4" Sch 80 fittings there; a T weighs about the same as two of my smaller guns. They're huge!
I don't know how much they cost, but I'd bet they weren't cheap.

Alrighty, I'm done with my triggered burst disc gun, except for the "disc popper" and the handle it attaches to. I have the perfect thing to use for a handle, but it's going to require me digging through my parts box (a miniature jungle).
