I needed something that would look decent on film, be able to take alot of abuse and not get destroyed. This is the solution that I came up with. I snagged a spirit halloween ghost trap to use as the starting point. Because it's decent sized and has lights and opening trap door.
However, the problem with this ghost trap was that there was no pedal and I had scenes where I needed to kick a pedal and close up shots of the trap. So I had to fabricate my own. What I did to build one was using parts I had laying around, I began laminating pieces of cardboard and foam, painting it with flexi-paint and attaching hoses and getting correct enough looking attachments to connect from the trap to the pedals and I was set.
Here's a gallery of the build.
