Her defense? She was "too broke to buy the chemicals" and take them home, police told Tulsa's Fox 23.
Surveillance footage shows Elizabeth Alisha Greta Halfmoon, 45, in the store for six hours before store employees decided to call the police. She had been trying to mix ingredients in the back of the store.
Even if the police hadn't arrived, Halfmoon wouldn't have been too successful. Officers at the scene said she was missing pseudophedrine, a key meth ingredient.
"She maybe didn't know how to do it," Corporal Scott Anderson told the Tulsa World.
But that doesn't mean Halfmoon’s cooking experiment wasn't dangerous. She was mixing sulfuric acid with lighter fluid in a bottle when police arrived, and some of the lethal chemicals had melted the paint off a nearby shelf.
Another Tulsa resident was arrested at the same Wal-Mart in October carrying what was essentially a portable meth lab, Fox 23 reported.
According to the Tulsa Police Department, 690 meth labs have been busted in the city since 2009. "We are definitely the meth capital of the state," a Special Investigations Officer told Fox 23 in an interview last March.
How the f**k you cook Meth in Wal-Mart?
