A first chemiluminescent fluid is disposed in a breakable container in the chamber, and a second chemiluminescent fluid is in the chamber. A tip assembly is attached to the housing and includes a nib movably disposed in the body, and a filter element may be positioned within the body to prevent passage of broken particles from the container to the nib tip. A resilient element is used to impose an outward biasing force on the nib. A porous material is disposed over an outer surface of the nib tip and securely held in place. The device is activated for use by bending the housing to break the container causing the first and second chemiluminescent fluids to mix and react, providing a chemiluminescent solution that flows to the tip assembly for dispensing onto a desired surface. ## Claims ### Claim 1 A marking device comprising: an elongate hollow housing having an inside chamber and extending from a housing first end to a housing second end, wherein the housing first end is closed;
