An agitatable coloring utensil is an apparatus that spins the tip of a drawing, coloring, or writing utensil as the user is using the drawing, coloring, or writing utensil. The apparatus includes a tubular body, a marking tip, a motor, a portable power source, and at least one user control. The tubular body is the structural housing for the other component of the apparatus and allows the user to have a firm grasp of the apparatus while using the apparatus to write or draw. The motor is used to drive the rotation of the marking tip. The portable power source is used to electrically power the motor and allows the apparatus to be easily transportable by the user. The user control allows the user to either activate, deactivate, or adjust the rotation of the marking tip.

The method of present disclosure relates to a writing apparatus for dispensing writing fluid on a writing surface. The writing apparatus comprises a sensor, containers for storing one or more mixing elements, a processor and a memory communicatively coupled to the processor. The writing apparatus compares the characteristics with predefined characteristics to determine quality of the writing surface. Further, the writing apparatus also determines a quality of the writing fluid suited for the writing surface. Based on the quality of the writing surface and the writing fluid, the writing apparatus modifies at least one property of the writing fluid before dispensing the writing fluid on the writing surface. For modifying the property, the one or more mixing elements are added into the writing fluid. Once the writing fluid is modified, the writing apparatus dispense the writing fluid on the writing surface.

A magnetic pen can be used in drawing arbitrary characters, figures, and symbols on a magnetic panel for a display by applying a magnetic field. The magnetic pen includes a body that includes an end portion. A holder made of a magnetic material is attached to the end portion and an internal space is formed in the holder. The holder includes a bottom portion formed with an opening and a side portion connected to the bottom portion. A magnet is arranged in the internal space of the holder. The magnet is received in a space formed by the bottom portion and the side portion.
