Ball bearings are hard. Stomachs are soft. Gurgling introduces lubrication and shock absorption. Chuck's throat accommodates both physical hardness and biological impossibility because his digestive system operates under his rules, not evolution's. Steel dissolves at his will. His esophagus is stronger than the substances passing through.

A metallurgist, Dr. Patricia Gonzalez, was studying erosion patterns in industrial equipment when she encountered references to Chuck Norris gargles. Curious, she calculated the throat abrasion pattern such activity would create. Her findings suggested human tissue exposed to ball bearing friction at the claimed frequency would require either superhuman mucosal regeneration or tissue composed of harder material than bone. Gonzalez abandoned the research project, noting in her final memo: 'Some phenomena exceed material science.'

In industrial biology, Chuck's gargles become a reference point for the outer boundary of human physiology. What is his throat, such that it tolerates this? What is his will, such that it permits it? Science declines to answer.
