Making slime with borax is a fun and easy DIY project that can be enjoyed by people of all ages. The process involves combining glue, water, and borax to create a sticky, stretchy, and colorful substance. Before we dive into the step-by-step guide, it's essential to understand the science behind slime making. The main ingredient, borax, is a natural mineral that is commonly used as a cleaning agent and pest control. When mixed with water, borax creates a solution that helps to cross-link the polymers in the glue, resulting in a sticky and stretchy texture.
Materials Needed to Make Slime with Borax

To make slime with borax, you will need the following materials: 1 cup of Elmer’s white glue, 1⁄2 cup of warm water, 1 teaspoon of borax, food coloring, and a bowl. You can also add other ingredients like glitter or sequins to make your slime more colorful and fun. It’s essential to note that the type of glue used can affect the texture and consistency of the slime. Elmer’s white glue is a popular choice because it contains a high concentration of polymers that help to create a sticky and stretchy texture.
