1
Fill a jar with warm water. Warm water rather than cold will help get the most ink out of the highlighter cartridge.
-
2
Cut the highlighter apart until you get to the center with the ink cartridge. Make sure to do this step carefully so that you won't accidentally cut yourself.

3
Make slits in the thin plastic coating that is on the highlighter cartridge. This will let the ink out of the cartridge.

4
Place the cartridge in the jar of water and allow it to soak for several hours. You want to get the most ink you can out of the cartridge.

5
Remove the cartridge from the water and place a lid on the jar.

Tips & Warnings
You can make these jars a day or two ahead of time. When you need to use them, simply mix or shake them up to redistribute the highlighter ink and set them out.
Use several different colors of highlighter to make different colors of glow jars. You can also mix colors to make a different color or shade of water for the glow jar.
Do not consume the water and highlighter mixture. The ink is toxic.
