Mourning Cemetery & Manor have a really good tutorial on how to build a bleeding tombstone.  The trick to this one involves two plexiglass blood tanks, the main tank is mounted in the styrofoam base and a secondary tank is mounted above the bullet holes.     A 1/2″  tube feeds the blood from the main tank to the secondary tank, while 1/4″ tubes drain the blood down into the bullet holes.  This setup allows for the blood to slowly seep out of the holes rather than flowing out at an unnatural rate.   Items needed to complete this include: 1/4″ Plexiglass tanks (width determined by tombstone) water pump (1) 1/2″ tubing (5) 1/4″ tubes Plexiglass squares Styrofoam tombstone 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.
