When using a tumbler, there are risks of getting burns or other accidents due to not being able to grasp the temperature of the contents within it. In order to provide a solution for this problem, a tumbler which can measure the temperature of the inner contents was designed. By utilizing the scientific principle of the change in density which occurs according to the temperature, the temperature of the contents within the tumbler can be easily seen through the changes in the liquid within the tube located on the exterior of the tumbler.
