Kids show off their one-of-a-kind creations at a market just for them. NY1's Shannan Ferry has that story from Corona. 

Owen Cirrito may only be 5-years-old, but he's already an entrepreneur. 

He created his own version of a toy which is designed to helps kids learn math. 

It's an idea that came easily to him. 

"It just wounded up in my head, and my schools super talented, it's a gifted and talented school," he said. 

Owen was one of about 40 kids who got to show off and sell their creations on Sunday. 

It was all part of a kid entrepreneur market called 'Muyu Market' which set up shop at the New York Hall of Science.

Organizer Margarita Soto said the goal is to give youngsters hands-on business experience.

"They have to learn how to create inventory, they have to do the math around that, create a price, to sell, to market, and so we think these are all skills that are transferable," she said. 

Those are skills the Scalzo brothers are learning quickly. They were selling dog treats and dog shampoo. 

"It's all natural, and it's like healthy for the environment," said Raymond Scalzo. 

There was a wide range of products available. Diego Gonzalez, 10, was selling books he wrote and self-published. 

"I wrote my books like why not make some money off of what, my work? Also, everybody is going to be selling something what's gonna make me unique right?  So I decided to throw in the book marks," he said. 

Diego wasn't the only one mastering the business world.

Luca, 7, sells fuzzy pencils, and said he's learned quite a bit too.

"Be good at advertising, but don't go too overboard with the advertising," said Luca. 

Kids may get more opportunities to put those tips to the test. 

Organizers plan to set up another market like this one in the future. ​
