The Oregon Department of Fish and Wildlife has created the world's most awesome squirt gun. The GHO Series Hydroblaster is a trailer mounted pressure washer that shoots 140 degree water at 3,000 pounds per square inch out of a 225 gallon tank. The sole purpose of the pressure washer is to blow away aquatic weeds and critters from boats and trailers so they can't "set up shop" in Oregon's waters.
