Slime has become a popular sensory activity for children and adults alike, providing a therapeutic and engaging experience for many individuals. It is an ideal tool for stress relief and offers endless opportunities for creative play. In addition, making slime can double as a fun and educational science experiment. However, some people may not be aware of the simplicity behind creating this gooey substance. In this article, we will discuss how to make slime in a few easy steps.

The process of making slime involves combining a few simple ingredients. By understanding the chemical reactions that take place, one can easily create slime at home with minimal effort. One of the most common recipes for making slime includes the following ingredients: glue, baking soda, and contact lens solution. These ingredients create a polymerization reaction, which results in the formation of slime. You can also add food coloring if desired.


  • 4 ounces of white school glue
  • 1/2 teaspoon baking soda
  • contact lens solution
  • food coloring (optional)


  1. To begin making slime, start by pouring approximately 4 ounces of white school glue into a mixing bowl. This glue will serve as the base for your slime and is essential for achieving the desired consistency.
  2. Next, add half a teaspoon of baking soda and mix well. The baking soda will help thicken the slime and create the necessary chemical reaction with the contact lens solution.
  3. After mixing these two ingredients, slowly add contact lens solution to the bowl while stirring continuously. If you want to add food coloring, mix it in with the contact lens solution. It is important to note that different brands of contact lens solution may yield varying results. For best results, use a solution that contains boric acid and sodium borate as these ingredients are crucial in the formation of slime. Continue adding contact lens solution until the mixture begins to form a ball and pull away from the sides of the bowl.
  4. Once your slime has reached the desired consistency, you can begin kneading it with your hands to further develop its texture. If the slime is too sticky, you can add more contact lens solution to achieve a firmer texture. Conversely, if the slime is too firm, you can add more glue to soften it.

Learning how to make slime is a simple and enjoyable process that can provide hours of entertainment and stress relief. By following these easy steps and understanding the chemistry behind the creation of slime, anyone can successfully make their own slime at home. With endless opportunities for customization and creativity, making slime is an activity that can be enjoyed by individuals of all ages.
