Hey, I'm working on my GB Halloween costume and I'm thinking about gettnig to work on the proton pack soon. I'll just have to use the tips from the site as my resource. But the gun is what I'm more worried about. What would a prop expert suggest? Could I carve up an old squirtgun or something?

I'm not a prop expert, but i've made an okay proton pack and gun. What I did was take some pvc pipe, and cut it up. I then took some connectors and connected the peices so that they'd look a little better. But i'd say that a water gun could work good if you did it right.
