Here are some toxic waste barrels that I made for my haunt 2007. I was trying to think of a way to make toxic waste look like it was really toxic. I wanted it to look alive, like lava-with lights flickering from inside and steam-fog. Here is what I came up with and it looks great in person. The orange ones looked live lava and was extremely convincing, and the green ones looked toxic.
Step 1: Step 1
I got some empty cardboard 55 gallon drums. I wanted them to look like the black and white steel drums, so we painted them. We spray painted them with black and primer grey, and we used duct tape to section them off where we wanted different colors.
Step 2: Step 2
I made some toxic waste signs on my computer and attached them using 2 sided tape. I attaced string lights by draping them down the outside of the barrel and covering them with foam insulation Great Stuff. I used 2 strands of lights, one flashing and one non flashing. Inside the barrel I put rope party lights because they are brighter and flash brighter, and create a better glow.
Step 3: Step 3
I cut out a square in the bottom and the backside of the barrel to put in a fog machine. In this picture you can see the inside rope lights on and the fog, but I didn't have the lights on in the front ooze running down the front of barrel. In this picture you can see that I painted some of the Great Stuff running down the barrel and it does make it look better when the lights are on, painting them helps add the color.
