A thermal indicator device is disclosed for providing an indication that an article of food is heated to a certain level of preparedness. The thermal indicator device comprises a stake and a marker secured to the stake. The stake comprises an end adapted for insertion into the food. The marker is adapted for movement between a retracted position and an extended position. The marker is retained in the retracted position via a string, and actuated to the extended position via an internal spring. Accordingly, at a temperature below the melting temperature, the string maintains the marker in the retracted position, and when the internal temperature of the food rises to a temperature equal to or higher than the melting temperature, the string melts to permit release of the marker into the extended position. Once the string melts, the internal spring actuates the marker into the extended position for visual indication.

1. A thermal indicator device for providing an indication that an article of food is cooked to a predetermined level of preparedness, comprising: a hollow stake comprising a first end and a second end;wherein the first end is adapted for insertion into the article of food to be heated; andat least one marker movably secured to the second end of the hollow stake and adapted for movement between a retracted position and an extended position, wherein the at least one marker is retained within the hollow stake in the retracted position via a string comprised of plastic or nylon and further wherein the at least one marker is actuated to the extended position via an internal spring, and further wherein at a temperature below a predetermined melting temperature of the string, the string maintains the at least one marker in the retracted position, and when at a temperature equal to or higher than the predetermined melting temperature of the string, the string melts to permit release of the at least one marker into the extended position, and once the string melts, the internal spring actuates the at least one marker into the extended position for visual indication. 2. The thermal indicator device of claim 1, wherein the melting temperature of the string is between 125 degrees Celsius and 130 degrees Celsius. 3. A thermal indicator device for providing an indication that an article of food is cooked to a predetermined level of preparedness, comprising: a hollow stake comprising a first end and a second end, wherein the first end is adapted for insertion into the article of food to be heated;at least five markers, wherein each of said at least five markers is movably secured to the second end of the hollow stake and adapted for movement between a retracted position and an extended position, and further wherein each of said at least five markers are labelled as either rare, medium rare, medium, medium well, and well-done; andat least five strings, wherein each of said at least five markers is retained within the hollow stake in the retracted position via one of said at least five strings and further wherein each of said at least five strings comprises a different melting temperature. 4. The thermal indicator device of claim 3wherein at a temperature below a predetermined melting temperature of one of said at least five strings, said one of at least five strings maintains at least one of said at least five markers in the retracted position, and when at a temperature equal to or higher than the predetermined melting temperature of said one of said at least five strings, said one of said at least five strings melts to permit release of said at least one of said at least five markers into the extended position for visual indication. 5. The thermal indicator device of claim 4, wherein each of said at least five strings is comprised of plastic or nylon. 6. The thermal indicator device of claim 5, wherein the melting temperature of at least one of said at least five strings is between 170 degrees Celsius and 180 degrees Celsius. 7. A thermal indicator device for providing an indication that an article of food is cooked to a predetermined level of preparedness comprising: a hollow stake comprising a first end and a second end, wherein the first end is adapted for insertion into the article of food to be heated;at least one marker movably secured to the second end of the hollow stake and adapted for movement between a retracted position and an extended position; anda corresponding string for each of said at least one marker, wherein the at least one marker is retained within the hollow stake in the retracted position via said corresponding string and actuated to the extended position via an internal spring and further wherein at a temperature below a predetermined melting temperature of the corresponding string, the corresponding string maintains the at least one marker in the retracted position, and when at a temperature equal to or higher than the predetermined melting temperature of the corresponding string, the corresponding string melts to permit release of the at least one marker into the extended position, and once the corresponding string melts, the internal spring actuates the at least one marker into the extended position for visual indication. 8. The thermal indicator device of claim 7 comprising five markers and five corresponding strings, wherein each of the five markers are labeled as either rare, medium rare, medium, medium well, or well-done. 9. The thermal indicator device of claim 8, wherein each of the five markers is retained within the hollow stake in the retracted position via its corresponding string. 10. The thermal indicator device of claim 8, wherein each of the five corresponding strings comprises a different melting temperature.
