RELATED APPLICATION INFORMATION [0001]This application claims priority to Provisional Application No. 60/845,701 filed on Sep. 19, 2006 and incorporated herein by reference. TECHNICAL FIELD [0002]The present invention generally relates to special effects technology and, more particularly, to a system and method where for a blood-hit effect without pyrotechnics. BACKGROUND [0003]Conventional techniques for achieving a bloody bullet hit on an actor include using what the industry refers to as a "SQUIB". The squib, in reality is an electrically ignited detonator that an actor wears on their person. The squib is backed by a steel plate to protect the actor from harm when the charge is detonated. On top of the detonator, a pre-manufactured plastic bag of stage blood is fastened. The whole setup is wire harnessed with a control cable connected to a pyrotechnic controller. The actor then places his costume over the blood bag/detonator/steel plate setup. [0004]A state licensed pyrotechnic operator is required to activate the detonator from the controller and the detonators explosive powers will burst through the blood bag and rupture the pre-scored/distressed area of the costume where this effect will reveal a simulation of a bullet hole with blood being ejected. [0005]The conventional blood-hit effects may be dangerous, and require bulky components, such as a steel plate. This limits the scenarios in which the effect can be used since the plate and the equipment is cumbersome. In addition, a pyrotechnic specialist is needed by law in many jurisdictions to activate the charge. This adds to the complexity of usage and the overall expense. [0006]Therefore, a need exists for a blood-hit effect that overcomes these disadvantages. SUMMARY [0007]A blood-hit effect system includes a pressure vessel and a solenoid configured to fit on a person. A hose connects to the solenoid and is filled with a fluid. A radio control device activates the solenoid to open to release air from the pressure vessel such that the fluid in the line is ejected from a nozzle located on the body of the person to provide the effect of being shot at the location of the nozzle. [0008]The nozzle may be located on the person at an arbitrary location. In one embodiment, a vest is provided with a plurality of predefined holes where the nozzle is installed. Multiple nozzles may be employed in communication with the same or different pressure vessels and solenoids. The effect hits may be timed to simulate multiple shots at different locations or at different times. [0009]An apparatus for a blood-hit effect includes a pressurized reservoir, a valve, and a hose having a first end portion coupled to the reservoir through the valve. The hose is configured to store an ejection fluid and the hose includes a second end portion. A membrane is configured to cover a second end portion of the hose. The membrane is disposed at a location on a subject where an effect is to occur. The membrane is configured to burst in accordance with an instantaneous release of pressure from the valve to eject the ejection fluid through the membrane. [0010]An apparatus for a blood-hit effect includes a pressurized reservoir having a controlled valve for releasing pressure in accordance with a control event, a hose having a first end portion coupled to the reservoir through the valve, the hose configured to store an ejection fluid, the hose having a second end portion; and a fitting connected to the second end portion of the hose and having an opening in fluid communication with the hose; and a membrane configured to cover the opening in the fitting, the membrane configured to burst in accordance with an instantaneous release of pressure from the valve to eject the ejection fluid through the membrane in accordance with the control event. [0011]In alternate embodiments, the apparatus is mounted on the subject where an effect is to occur. A garment may be mounted on the subject where an effect is to occur and configured with at least one hole, the at least one hole being dimensioned and configured to receive a fitting on which the membrane is connected, wherein the membrane is disposed at least flush with a surface of the garment. The at least one hole may include a plurality of holes formed at a plurality of locations on the garment. The garment may include a vest which fits under a wardrobe item. The second end portion may include a fitting and an open ended cap such that the membrane is secured between the fitting and the cap. The cap preferably includes an inner circumference having a knife edge for contacting the membrane. The fitting may include a flange. The apparatus further includes an electrical power source for controlling the valve and the valve includes a normally closed solenoid valve. The valve may be controlled remotely. The membrane preferably includes a polymeric material stretched across a seal ring. The ejection fluid may include at least one of a colored fluid and particulate matter.
