A styrofoam tombstone is about the simplest prop you can make for your haunt assuming you don’t make it overly intricate, but sometimes even the simplest of props can take on a whole new life by adding a motor. Just ask Christoper, of Chris’ Crypt who has a really simple tutorial on how to turn your Styrofoam tombstone into a rocking tombstone.  You’ll need to build a wooden base to hold the tombstone on one end (pivot point) and the motor on the opposite side.  When you connect the cam to the tombstone the slow rotation of the motor will get your tombstone rocking back and forth.   Items needed to complete this include: Styrofoam tombstone Motor Wood for base 1/2″ piece pvc Shop These Materials on Amazon 12V Wiper Motor 2.5" Shaft 110 Degree (prop building) PWM DC Motor Speed Controller 9-70V 35A 45Kg High-Torque Waterproof Digital Servo Motor XPS Foam Board 1" Thick Craft Sheets 4-Pack 4-in-1 Hot Wire Foam Cutter Kit 15W Loctite Power Grab Foam-Safe Construction Adhesive 5-Pack Foam RIP Tombstone Blanks for Carving Decorative Cemetery Fence Sections Rust-Oleum Flat Black Spray Paint 12oz Affiliate Disclosure: HauntersList.com is a participant in the Amazon Services LLC Associates Program.
