And the river turned to...animal fat?

HuffPost reports:

Workers with the U.S. Coast Guard and the Texas General Land Office used pitchfork and fishnets Wednesday to pierce, corral and remove chunks of beef fat clogging the Houston Ship Channel, shutting down nearly a mile of one of the nation's busiest marine arteries...

Some 15,000 gallons of animal fat poured into the channel through a storm drain on Tuesday after an onshore storage tank owned by agricultural company Jacob Sterns and Sons leaked 250,000 gallons of the greasy substance, Brahms said...

"When it hit the water it instantly thickened," Brahms said. "It turned into a thick pattie, which is pretty much what we're cleaning up now."

In the first of the Ten Plagues, Moses turns the main Egyptian waterway to blood:

This is what the LORD says: By this you will know that I am the LORD: With the staff that is in my hand I will strike the water of the Nile, and it will be changed into blood. The fish in the Nile will die, and the river will stink; the Egyptians will not be able to drink its water. (Exodus 7:17-18)
