How to make glow in the dark ink

There are two ways to make glow-in-the-dark ink. First, you can purchase the materials for a ready-made glowing ink from a craft store. If you are a beginner working at home, use that method. You can also make a glowing ink substance with chemicals in a lab. This is a science demonstration that should NOT be attempted at home. Phosphorus is very poisonous.

    Make Glow Ink From a Kit

  1. 1

    For home use, mix together glow powder from a craft store and ink, according to the directions on the packaging.

  2. 2

    Choose your colour. Different colours of glowing ink will glow for different periods of time, varying from 30 minutes (purple) up to 12 hours (green).

  3. 3

    Use a syringe to load the mixed ink into a pen or an ink cartridge, if you have mixed the powder with printer ink.

    Make Glowing Ink in a Lab

  1. 1

    Wear protective gear appropriate for a chemistry lab, including eye goggles and gloves.

  2. 2

    Combine phosphorus and oil of cinnamon in a small glass bottle.

  3. 3

    Screw on the cap tightly.

  4. 4

    Heat water in a beaker over a Bunsen burner to make a warm water bath.

  5. 5

    Put the bottle into the warm water bath and heat until the ingredients dissolve.

Tips and warnings

  • Glow powder can also be added to paint.
  • Phosphorus is poisonous. Do NOT try the second method unless you are experienced in working safely in a lab with toxic chemicals.
