Easy to use and set up. Crowd sounds jeer and mock. The blade comes screeching down at high speed and a strobe light kicks in as your patrons are sprayed with blood (water). An unsettling effect that sends them running and screaming! Includes body, table, headbox, blade, squirting mechanism and tank, 2 tape players, 2 tapes and loud amp with speakers. Requires 100 psi air compressor and A/C power.
