I made this two packs three years ago.
First pack is made with the protective lid of my stereo, cassette cases, the moulder of a cosmetic box, tube, a neon flashlight, wires, protective tube for wires, the moulder of a kit called "star machine", del light, switchs, a board game, strap, and I used hot glue to hold togheter all the stuff. It need 60 volts to light everything up and it weight close to 20 lbs. I need to review all that.

The other pack is a fantasy. I made it for my sister for halloween. Its kind of a new pack generation but I smile when I think about Extreme Ghostbusters. Everything hold on a paint pan. Im not sure of the word in english. 18 volts (maybe a little more) and it weight very light. Both guns are made with a plastic box cards, tube, fuse, pen cap. My english is not good enough to describe everything.
