That means that in the relation considered, any object relates to itself: For any "x", relation(x, x) is true. For example, this is a property of equality (any number is equal to itself), of congruence (any object is congruent to itself), and to relationships such as greater-than-or-equal (any number is greater than or equal to itself) and the non-strict subset relation (any set is a subset of itself).

How do laser tag beams show up in black lights and how can i modify my toy guns to do the same?
The ability to see laser beams has nothing to do with black lights. Lasers need a reflective property in order to be seen by the human eye. Often times, the reflective property is a simulated fog in laser tag arenas. Something as simple as air freshener can be used as a reflective property in order to see a laser beam.

What do reflective materials have in common?
Reflective materials have the property of bouncing back light that falls on them, increasing visibility and improving safety in low-light conditions. They are often used in various applications, such as traffic signs, safety clothing, and bicycle reflectors, to enhance visibility and reduce the risk of accidents.
