     The sound suppression system consists of plastic bags filled with water
strung across the SRB holes in the pad, and six largest sprinkler heads you
have ever seen.  The plastic bags were added after STS-1.  They absorb the
ignition pulse of the SRB's by simply being vaporized.  The sprinkler heads
are about 8 feet tall and consist of a 40 inch pipe with an angled plate
above the open end to spread the flow.  They together throw 600,000 gallons
of water all over the pad to keep it from catching on fire and soak up some
of the sound energy.
