This is a pop-up turkey timer. Basically, there a soft metal or wax plug in the bottom. When it gets to a point where it melts, the red stick indicator is released and pushed out by the spring. Make sure the metal or wax melts at an appropriate temperature (165 F if I remember my food safety license video correctly) and you have turkey that won’t give the entire family salmonella or
ebola e coli.
Happy Thanksgiving everyone!
