12-Year-Old Slime Glue Entrepreneur Attempts Guinness World Records™ Title

DIY Slime is all the rage right now and for good reason. It is easy(ish) to make, can be any color, design you want, and is FUN to create. But for 12-year-old Madison Greenspan, she has built a business out of the slime world by launching her own successful slime glue company called Maddie Rae’s Slime Glue. And now she is taking it even further, by attempting a world record!

Greenspan has officially received the green light from GUINNESS WORLD RECORDS to move forward with her dream to attempt to break the record for the world’s largest slime. She plans to make over 6 tons of slime – that’s over 12,000 pounds!

Her world record attempt is scheduled to take place at 11am on November 4th at consumer toy show Play Fair New York (BOOTH #152), held at the Jacob K. Javits Convention Center in New York City. While no one has ever made slime close to this magnitude, Guinness World Records™ has identified the weight of 5,000 kilograms or 11,024 pounds to be crowned World Record Holder.

Breaking the record for the world’s largest slime would be so awesome,” said Maddie, adding, “we have been making really big batches of slime every week and it’s been so much fun! The best part is that after the event is over, I’m going to sell containers of the slime on my website and give the money to Hand in Hand to help the hurricane victims.  I’m so happy that I can have fun and help people at the same time.”

Even more amazing, once Greenspan completes the attempt, 3,000 slime jars will be filled with the record-breaking slime and given to Play Fair attendees as a souvenir, while the other 2,000 will be sold online with all proceeds going to Hand in Hand, a hurricane relief charity that was selected by Madison.

 “Madison’s drive never ceases to amaze me,” stated Howard Greenspan. “Her sheer determination and dedication to her glue business and to this record breaking attempt is well beyond her age.  I’m very proud of her.

The origins of her brilliant new business started last year when Greenspan became increasingly frustrated at the glue shortage that we experienced last Winter. She pleaded with her dad to help her make her own brand of slime glue. As the owner of a consumer products company, Madison’s father, Howard Greenspan knew he could turn around the product quickly and help Madison fulfill her dream, offering her a real education in business. After lots of hard work, Maddie Rae’s Slime Glue was born! Today, many thousands of gallons of glue have been sold, and she has expanded the line to include slime coloring and slime jars.

In addition to Madison’s record breaking slime attempt on November 4th, she will be participating at a special Meet & Greet at her Maddie Rae’s Slime Glue booth (BOOTH #311, 3-7pm) where she will be giving slime making demonstrations, signing autographs, taking pictures and helping kids make their own take-home slime from the booth.


Play Fair will entertain more than 30,000 kids and parents over the Nov. 4-5th weekend, making it the perfect venue for the largest slime attempt. The event offers hands-on exhibits, awe-inspiring displays, dozens of toy and entertainment brands, and never-before-seen exclusives that attendees can feel, touch, and take home.
