Okay so here's the start of my new prop for this year. The idea is sheet metal roofing used to patch a containment fence and zombie rattles and shakes the sheet metal until it comes loose and falls off. Zombie then lunges forward through the gap. Sirens go off, etc...
Sheet metal is actually pvc plastic to keep weight down and clearly needs distressing. I'll update this post as I progress the project over the next few days. Can't wait for Halloween!
