MIAMI (CBSMiami) —  Lulu’s Nitrogen Ice Cream shop in Miami Beach has customers getting a sweet treat but also a lesson in science.

CBS4’s Lisa Petrillo knew she was in for a sweet treat but not for everything else.

Meet Luisa Santos – a Columbian-born, Miami-raised entrepreneur – who had a passion for sweets and science while attending Georgetown University a few years ago.

“I was actually in my senior year at university and learned about this way to make ice cream out of liquid nitrogen. I was completely captivated and thought it was the coolest thing,” said Luisa.

She started selling at area farmers markets and it became a huge hit.

“So I decided there was enough demand that I could come home and open shops where I grew up in South Florida,” she said.

She opened the first Lulu’s on 22nd Avenue and Biscayne Boulevard in May of 2015. Recently, she opened her second shop on Miami Beach.

So how does it work? It all begins with a cow named you guessed it “Lulu”.

It all begins with a cow named, you guessed it “Lulu.”

“There’s a real Lulu, a real cow. She weighs 2,000 pounds! She’s awesome and a great cow. She lives at the farm. We get the milk and cream from her,” said Luisa.

Lulu and her other cow friends provide nature’s materials then Luisa merges them with science.

“This is liquid nitrogen. It’s negative 321 degrees Fahrenheit. It’s a liquid when it comes out but when it hits the ice-cream it begins to boil off and when it boils off it creates that awesome fog,” Luisa explained while showing off a bowl full of fog.

The result is a rich and creamy ice-cream made to order entirely from scratch such as Petrillo’s waffle cone. The cone is first pressed, heated, flattened–rolled and then, with a cauldron of fog, her vanilla cone with caramel sauce and rainbow sprinkles is created!

“It is creamy and delicious and it doesn’t feel heavy, not too sweet. It feels homemade and this waffle cone is to die for,” Petrillo said while biting in.
