Kids love slime, but us parents hate the mess that comes with it. That’s why we created Magic City Slime Activator – to take the mess and the guesswork out of slime-making.  Now you and your kids can make perfect slime in 3 simple steps!

Our Slime Activator is:

  • Made in America and manufactured with the highest quality standards
  • Independent laboratory tested and certified, child-safe formula
  • Concentrated - a little goes a long way

  2. Add 1-2 tbsp. of Magic City Slime Activator
  3. Mix well until desired slime consistency

*If you're adding color to your slime, for best results mix it with the glue before combining with activator.

  2. Too watery --> Add Glue

About Us

We have kids—they love making slime! We don’t get it either, but at least they are not in front of the TV or iPad!

We experimented with numerous household products in our quest for a safe, DIY slime activator – but nothing gave us that perfect slime result our kids were looking for.

So after extensive laboratory testing we developed our very own slime activating formula – it worked, was safe enough for our own kids and Magic City Slime Activator was born!

Quality control and safety are important to us, so we partnered with an established manufacturing company in the United States to manufacture and package our product.  We are proud that Magic City Slime Activator is made and packaged in America!

We want you to be 100% satisfied with your purchase. If for any reason Magic City Slime Activator does not meet your expectations, we'll refund your order in full, no questions asked.  We take pride in what we do and are committed to providing you with the best possible customer experience.

We believe in encouraging creativity and play in children.  A portion of the proceeds of each sale of Magic City Slime Activator will be donated to nonprofit organizations that provide artistic opportunities to children.
