Elmer's Magic Liquid for slime, in a 259ml bottle, is the activator that transforms Elmer's school glue into slime, replacing the use of borax or contact lens solution. Simply mix it gradually with the glue until you obtain the desired texture. The formula is washable and non-toxic, designed for home use with adult supervision, and does not cloud the final result — it works with both classic white glue and the transparent version, maintaining the opaque or crystalline effect of each. This magic liquid is the indispensable complement for those who already have Elmer's glue at home and want to make homemade slime without resorting to less safe ingredients or improvised recipes.
