Good recipes for making slime include the borax-based recipe from Steve Spangler Science and liquid starch slime from the Little Bins for Little Hands blog. Many homemade slime recipes call for borax, which may be a safety concern if the slime is for young children. Liquid starch-based recipes, such as the one from Little Bins for Little Hands, are alternatives to borax-based recipes.
The Slime Party recipe from Steve Spangler Science calls for Elmer's glue, borax, water and food coloring. To create the slime, pour the bottle of glue into a mixing bowl, fill the empty glue bottle with warm water, shake the bottle and add the contents to the bowl. At this stage, add a few drops of food coloring if desired. Mix half a cup of warm water and a teaspoon of borax in a cup, and slowly add the borax mixture to the glue while stirring. Store the finished slime in a zip-top plastic bag.
To make liquid starch slime, combine half a cup each of water and Elmer's glue. Carefully add this mixture to half a cup of liquid starch. Add variation by experimenting with different additions, including sand, confetti, glitter or small items, such as buttons.
