Supplies

    Step 1

    Fluorescent dye glows a bright neon yellow when exposed to an ultra violet light source. This is ideal for dying T-Shirts and coloring paper, however, some fabrics may not "stain" very well.

    Step 2

    Open the highlighter and carefully slide the stick of colored ink out.

    Step 3

    Hold firmly and squeeze over a container.

    Step 4

    A small highlighter will yeld about 50ml of glowing diluted fluorescein.

    Step 5

    After squeezing a lot, the stick should look like this, completely white.

    Step 6

    Now turn on the UV light, the liquid should emit an eerie green glow.

    Step 7

    The liquid will keep its glow as long as you want, regardless of how much liquid you used.

    Step 8

    Step 9

    It works with big amounts too, just add a lot of water.

    Step 10

    This can be frozen, and it won't lose it's glowing properties.

    Step 11

    I only used gloves to prevent the ink from staining my hands. If the label on the highlighter says "Non-Toxic" then you should be fine with out them, however don't drink the ink or put it in your eyes
