Cringe Devices

The cringe devices explore the relationship between function and purpose. They fulfill their purpose by creating gut-wrenching noises, yet are rendered functionless because no one would willingly subject themselves to auditory torture. If the cringe devices are functional through fulfilling their purpose, but that purpose is undesirable, can they still be considered functional?
The devices generate sound by scraping various materials against each other in different ways. The handheld slide cringe device (pictured first) uses metal on marble and a back-and-forth sliding motion. When the user slides the lid of the box cringe device (pictured second), styrofoam scrapes against marble. The twisting cringe device (pictured third) generates the sound of metal scraping sandpaper and ceramic when its user twists its cap. These motions cause the user to create a viscerally disturbing sound as they explore the function of each piece.
