Slime is sublime for Cheyenne brothers Mark and Joe Whiteaker.

The savvy entrepreneurs run a thriving business called Dope Slimes that makes and ships homemade slime across the country and to other parts of the world.

Slime is a gooey and stretchy substance that is taking much of the globe and the Internet by storm. Slime’s history goes back 30 years, but it has become wildly popular now, especially among kids who like to make it. 

“Slime looks so amazing,” Mark said during an interview with Cowboy State Daily as he gently pushed his fingers deep into a thick layer of fresh slime.

The brothers make about 100 varieties of slime in different colors, textures and scents. They package their slime in clear plastic containers and sell it on their website and platforms like Etsy and eBay. They also post their own videos on Instagram to show how to make perfect slime.

Slime creators use social media sites to market their work, Joe said, adding that in one month, anywhere from 500,000 to 1.5 million searches for “slime” are logged on Google.

Mark, 16, is the creative force behind Dope Slimes. 

Using a simple recipe — “Elmer’s (white school) glue, Borax and water,” according to Mark— the brothers and a few of their employees stir the ingredients using large stainless steel industrial mixers. Then Mark’s imagination provides the magic, as he creates a wide variety of slimes — from banana to funnel cake.

Mark’s slime is known for its distinctive aromas. A fluffy cloud slime called Lavender Dreams has the pleasing scent of the flower. 

DIY Pizza Kit combines five scents to create the smells of pizza sauce, cheese and buttery dough. Cotton candy bubblegum smells as good as it sounds.

Texture is also important for excellent slime. 

“Say I’m doing a slime inspired by an ice cream. I’d like to make the texture like ice cream,” Mark said.

Mark began making slime in the eighth grade for fun. “It’s stuff to do when you’re bored,” he said. 

He started the business when he was 14, but couldn’t keep up with the demand. 

Joe stepped in to help and is now an integral part of the business.

Joe, 24, handles the business end from customer service to packaging, labeling and ordering. He also manages the company’s website, which includes photos and commentary about each slime type. Although Joe earned a bachelor’s degree in mechanical engineering from the University of Wyoming in May, he plans to continue working with slime.

The brothers have sold more than 150,000 slime products (they also make dope putty) and their slime has won awards for its quality. 

Slime has given them a taste of celebrity as they have been invited to attend many slime conventions throughout the country. These expenses-paid trips soon will include one to a convention in Brazil. 

They have become well known partly because of their 500,000 followers on Instagram.

Two of the leading YouTube slime experts have noticed them, too. Karina Garcia, also called the “Queen of Slime,” and Talisa Tossell of London, England, gave high praise to their slime in online reviews.

The brothers are gearing up for a busy Christmas season.  

“We take it pretty seriously. It’s not just a side business,” Mark said.
