Ice Tray-Refrigerators

Ice cube trays are designed to be filled with water, then placed in a freezer until the water freezes to ice, producing ice cubes. Trays are often flexible, so the frozen cubes can be easily removed by flexing the tray. Twist ice trays have a simple spring loaded mechanism with a lever that is used to turn the tray upside down and flex at the same time such that the cubes drop are collected in a removable tray below and return the ice cube tray to its upright position without removing it from the freezer. The tray has to be removed to be collected and the ice cube tray has to be removed to be refilled.
