First we had the Dallas pot brownie case. You know, pot brownies -- those infamous "weapons of mass destruction."

Now we have this:

WALDO, FL -- Detectives say it's an act of local terrorism. An adult bookstore is cleaning up after a chemical attack by a homemade device that investigators are calling a "weapon of mass destruction."

In Waldo, people have held prayer vigils and protests aimed at an adult bookstore along US 301, trying to keep the "Cafe Risque" from opening its doors on time.

Those efforts have all failed, so investigators say it looks like someone has turned to what they're calling a clear act of terrorism to keep the store's owner from opening up shop. The device, discovered Sunday morning, was made of two gallon-size sports drink jugs connected by hoses. Someone set it on top of the store's window air conditioning unit.

Detectives say that person then strung one hose from a water spigot on the outside of the building, and pushed another hose into the building through a gap above the air conditioner.

"That water hose would churn it up, mix it up in the gallon jug, and enter it into the building," said Alachua County Sheriff's Sergeant Keith Faulk..."We haven't identified what was actually in the bottle, in the system that delivered it into the building. We do know that it was caustic, it was corrosive, it had a high pH level."...

Investigators say the state Department of Environmental Protection will test the contraption in its labs Tuesday to figure out exactly what was inside.
