Product Description Simulaid Simulation Blood Packet for FEBSS™, HydraSim™, and HydraSim™ SP. We recommend to use half the blood powder package per three gallon tank plus 1 cup of detergent (Dawn dish soap works the best) to help the simulation blood wash out of clothing. Users can use a wide variety of simulation blood as long the viscosity remains similar to water. Please read the Instruction manual of the FEBSS or HydraSim system for more information about the preparation of the simulation blood.
