I am thinking of doing a toxic waste set up, I have several 55 gallon barrels that I will be spray foaming and running green rope lights through them. I will be wearing a gasmask and one of those biohazard type plastic suits. I may also try running water through one of the barrels using a pump system and having it run into a big pit. Does anyone else have experience with this type of stuff? Any tips? Any cool ideas you'd be willing to share?
