________________________.A little metallic bead deep in the device held a spring in place, and the soft metal was supposed to liquefy when Tom Turkey reached 82 degrees Celsius - the temperature when fowl is safe to eat. This would free the spring, and up would pop a plunger to announce the bird was ready. 装置深处部位的小金属珠将弹簧固定在一定的位置，当烘烤的雄火鸡温度达到82摄氏度-鸟类安全食用的温度时，软金属被液化凝结。这样弹簧就可被释放并向上弹出一个活塞以宣告鸟类已经烤熟。
