"Brains.... more brains..."

"Bob" the zombie is made of fiberglass and uses a PVC ram and a waterpump to raise and lower in the water. He was supposed to be triggered by motion sensor, but I ran into a shortage of them and substituted an on/off heat switch that worked nicely. I added a strobe light hanging over him to trigger when he raised in the water. It was a subtle but interesting effect. I need rebuild him lighter and lower to really pop out of the water next year. Unfortunately the $30 refurbished water pump didn't last long so that will need replacing also.
