Palate Expander

A surprisingly legal torture device created by orthodontists that would be the worst way to die in the middle ages if you turned it multiple times a day, it works by turning a key in the thing to slowly expand your jaw to be wider. Is usually followed up by another legal (arguablly worse) torture device. (Braces)
