DIY Blacklight Paint

Measure and Mix

• 1

  Purchase a commercial liquid laundry detergent containing a whitening agent. Avoid using "gentle" detergents designed for delicate fabrics, as these do not contain the necessary ingredients and will not produce a glowing effect under a blacklight.

• 2

  Mix a solution of one part detergent to one part water in a plastic spray bottle. This mixture will add a subtle glowing appearance to surfaces.

• 3

  Use undiluted detergent to paint the room and make objects glow brightly under the blacklight.

Paint

• 4

  Paint the undiluted detergent on nonporous surfaces, such as plastic, glass and tile or disposable surfaces such as poster board using a paintbrush or sponge. Create designs, words, shapes and pictures that will glow under the blacklight.

• 5

  Spray the diluted detergent mixture on windows, mirrors or plastic sheets to create a subtle glowing effect over large areas.

• 6

  Dip black yarn or string in laundry detergent and let it dry. Wrap the string around objects and hang it back and forth across the ceiling.

• 7

  Wash white clothing, curtains and other fabrics in brightening detergent to make them glow more intensely under the blacklight.
