Young Entrepreneurs Showcase Businesses In Expo At Greenwood Cultural Center Some talented Tulsa kids are showing off their businesses Thursday night at the Greenwood Cultural Center, selling all kinds of products they’ve made by hand. Coordinators say this time in Tulsa's history is so important to inspire young entrepreneurs. Every business owner at the expo is under 18 and they're showing off everything from artwork to soap to candles - even slime. About 35 kids set up shop at the Greenwood Cultural Center, all with innovative businesses they're trying to grow. "I see a lot of young people doing stuff like this. I wanted to see what it was all about," said Kavaei Patterson.
