JEFFERSONVILLE, Ind. (WDRB) -- They can't even do algebra yet, but a pair of southern Indiana sisters has figured out the formula to build a business.  

Katie Wilson, 12, and her 10-year-old sister Jackie have grown a hobby into a brand and become Jeffersonville's youngest entrepreneurs.  

A sweet smell brings big business to tiny tycoons in Jeffersonville.

"Smelly Jelly is a flameless, wickless candle. You don't have to light it, burn it or heat it. All you have to do is take the lid off," Katie said about her new product.

Katie Wilson and Jackie launched JK Beads, a handcrafted jewelry company at the end of 2012.

Last year, they added Smelly Jelly to their catalog and started building a bankable brand.

"These girls doing it on their own just fascinated me and they're just cute," said Amy Gillam, who carries Smelly Jelly at Chateau De Pique in Clarksville.

The girls designed fragrances after the company's signature wines.

"It's been great, we've had multiple orders and every time they come in they end up selling, so we're low on our stash right now," Gillam said.

With 105 different Smelly Jelly scents, the girl's products are now in 13 retail locations throughout southern Indiana.

"So how do you make it?" asked WDRB's Gilbert Corsey.

"What you do is you grab a jar," Katie said. "And then you add one of these, which are our water beads."

"The beads will  suck up the water so it gives out the fragrance."

We can't reveal all the tricks of the trade.

Though the sisters say a sprinkle of this and dash of that earned them $60,000 in sales in less than two years.

"My friends think like it's awesome," Jackie said.

They started the company with inheritance money after their grandmother passed away. Children can't write checks so their mom is the CEO, but she's quick point out -- they run the show.

"The girls run the company when we go to craft fairs they are the one who are there selling their products, they decide what is going to be sold I have very little input or say," said Ann Wilson.

Teaching them a bit of responsibility along the way.

"Right now we have to pay our cell phone bill, and then the money -- after that we put it in the bank to save," Katie said.

It is the sweet smell of success.

"I think we are doing good," Katie said.

The girls actually sponsor craft shows and donate a portion of the proceeds to Relay for Life in honor of their grandmother, who helped them get the company off the ground.
