What's the Boom Boom Room?

Boom boom room was where they kept the special effects thing, not for visual effects. They kept fireworks there, with matches in the same box. Also had two 200 amp panels, fuse boxes for the whole studio. We got out that othere, but it rekindled thre's no fireworks in there. Or at least there's no gunpowder. I've always thought thermo nuclear fusion made the best moonshine or hooch.
