Pour 1⁄2 cup (120 mL) of water and 1⁄2 cup (120 mL) of white or clear school glue into a bowl. Stir them together with a spoon until the consistency is even. Choose a washable marker for your color. You can use any color you like, or combine 2 or more colors to make a new color. Grab the end part with a pair of pliers or a wrench and twist it off to remove it.  For example, you could use a red marker for red slime, or combine red and blue markers for purple slime. For scented slime, use a scented marker. Hold the felt cartridge above the glue, then squeeze it with your fingers. The ink is very concentrated, so you won't need very much. Remember, you can always add more later. If the color is not bright enough, squeeze another drop of ink into the glue, and stir it again. Keep in mind that white school glue slime will always have a slightly pastel shade unless you add a lot of color to it. You can store your finished slime in a zippered bag or resealable plastic container for several weeks. Keep the slime clean and put it away after each use. Make a new batch after it starts to dry out.
