In 2009 Buckyballs, a desk toy comprised of tiny, powerful magnets, started flying off the shelves and into the shopping baskets of fidgety-handed customers. Serial entrepreneur Craig Zucker, the product's creator, saw it reach $10 million in sales that year. Today Buckyballs are a sad chapter in the history of consumer product regulation. The federal Consumer Product Safety Commission (CPSC) drove Maxfield & Oberton out of business on shaky grounds. Now, as Jim Epstein shows, the agency is targeting Zucker himself in what appears to be retaliation for speaking out about the case.
