Is it troublesome to use stirrer when making coffee? The seemingly normal mug with a gadget similar to that powering the Pull-back car will be of great help. All you have to do is rotate the bottom part of the mug. The rotation will successfully stir the beverage without the use of the spoon.

Detailed instructions
The fan blade design on the bottom of the cup helps to melt the beverage evenly. With rubber tubing extended, the release of the rubber tubing provides the power to rotate the bottom of the mug and stir the beverage as a result.
