Slime activator is a liquid solution that is mixed into glue or other slime bases to make it into slime. The activator reacts with the ingredients to make it all stretchy and slimy. The most common slime activators are borax, borid acid, and sodium borate, which all work as activators to make the perfect slime. Other options include liquid starch, contact solution, and baking soda. Here are some recipes for making slime activator:

• Borax Powder: Borax powder is the most widely known slime activator and contains borax or sodium tetraborate. It is the most effective activator and produces the best slime.

• Baking Soda: A simple and effective baking soda slime activator you can make is four pinches (about 1/2 tsp.) of pure baking soda and 3 tablespoons of multi-purpose contact lens solution.

• Contact Solution: Contact solution and baking soda are simple to use and probably one of the easiest activators to use. It is important to make sure to use Contact Lens Solution that contains boric acid and sodium borate.

• Liquid Starch: Liquid starch is another popular activator that can be used to make slime. It is made by mixing 1/4 cup of liquid starch with 1/4 cup of water.

Making slime is actually a great science experiment and a fun way to teach kids. It is important to note that while borax is a common activator, there are other options as well.
