Expect unexpected the

One-of-a-kind company Surprise Industries is prepared to amaze you

As circus performer Claire de Luxe strode through the door on stilts, a Manhattan couple’s reaction was just what an enterprising business was hoping for: surprise!

“We’re gonna add about two-and-a-half feet to your height,” de Luxe told her newest pupils as she confidently criss-crossed the theater rehearsal room.

De Luxe’s private stilt-walking lesson was an unusual date night in more ways than one. It was also a service from Surprise Industries, a one-of-akind company founded by sisters Kat Dudina and Tania Luna.

In the three years they’ve been open, the siblings have provided more than 1,500 surprises for customers who answer a detailed questionnaire about allergies, phobias and disabilities — and good and bad past surprises in life.

“There’s nothing like the satisfaction of seeing someone pleasantly surprised,” Dudina said. “You see on their face 10,000 emotions.”

Mini-surprises, experienced with a group, are $50 a person. A pair of private surprises plus a surprise dinner runs $600 for a couple.

Heather Zeller bought one such surprise as a gift for her fiance.

“In his Valentine’s card I put a little print-out of the ticket,” said Zeller, 38, a Manhattan sales manager for an Internet radio station. “I told him, ‘I don't know what this is, but we’re going to find out together.’” The couple initially ended up in a flamenco class. “I’m very good at planning the traditional evening of going out and picking restaurants,” said Zeller’s fiance, Simon Olenick, 36, a consulting associate. “It’s good for someone to inject some imagination.” They came back for more. In a rehearsal room on 14th St., Olenick sat on a table as de Luxe strapped his legs into the stilts.

“Getting up is the hardest part,” de Luxe told him. “Push yourself up and I’m gonna grab you.”

As his fiancee snapped pictures with her smart phone, Olenick wobbled upright.

“It’s balmier up here,” he joked. “I wish I had a basketball and there was a hoop.”

With one hand on the wall and the other in de Luxe’s, he made his way down the room. “It’s all about a different perspective,” he beamed. De Luxe turned up the techno music on a boom box.

“Groove to it,” she commanded. “Your body knows what to do a lot better than your brain right now.” Soon, Olenick was moving nearly unaided. Next it was Zeller's turn to give stilt-walking a go. As she strapped her legs in, she turned to her fiance.

“What do you think for going down the aisle?” she asked.

The couple are to marry in three months.
