A closer look
Chemistry is a cruel mistress for the modern bank robber. When thieves grab stacks of cash embedded with exploding dye packs, the bills get permanently stained with a bright red, traceable chemical. In a desperate bid to salvage their loot, amateur criminals frequently toss the radioactive-looking money into a bucket of bleach to strip the color. Unfortunately for them, US currency isn't paper—it's a cotton-linen blend. The bleach aggressively breaks down the fibers, turning their stolen fortune into a worthless, soggy pile of white mush.
