Plot hole: One of the bank robbers, a former soldier, Ray Merrimen just got paroled 8 months ago for a previous felony. This film takes place in California. Convicted felons are prohibited by law from touching or owning firearms. Merrimen is at a public shooting-range with CCTV shooting his firearm. The police officer tracking him since he's a suspect in a new string of former and recent holdups walks into the shooting-range and they just stare at each other. He could've been busted and sent back. (01:03:45 - 01:06:00)
Plot hole: The whole timing in the count room at the Reserve scene is off. If he allegedly stole $30 million there's no way he could've done it in those few minutes. (01:36:00 - 01:41:00)
Answer: Considering how microwave ovens work, it seems it would. Microwaves work by bombarding whatever is inside with actual 'microwaves' which works to excite the water molecules within. Paper, and in the case of cash, cotton, wouldn't be affected on its own but the water inside would be. Ever had something wrapped in a paper towel when you microwave it? The cash is not metal, and the water content is what gets heated up inside and evaporated, so I believe it would work.
