Make a deluxe copper marshmallow shooter



You are probably already familiar with the PVC pipe marshmallow shooter, a classic, fun weekend project. Maybe you already have one. Next time you show up for some gooey, air-powered confectionary warfare, why not come packing some classy heat — the Deluxe Copper Mini Marshmallow Shooter Mk. II!

You’ll build it from lengths of copper pipe and standard fittings. The Dremel Multi-Max will cut your 1/2″ dia. pipe to length with ease, so no more laboring over a hacksaw. Finally, you’ll need some basic pipe soldering skills to put it all together.
