While Elsa builds her ice castle with magic, Brent Christensen and his team build real frozen fortresses with their hands.
"We have an icicle farm at each location," Christensen said.
1) Grow the icicles. An elaborate sprinkler system sprays water on to a metal fence.
"On a little 4x4 chain link fence gate that's up on stilts, we can grow hundreds of icicles on one of them and we have 20," Christensen said.
Those farmers (as they're called) can grow up to 5,000 icicles per day.
2) They are harvested, dipped in water, and stuck together with a snowy mixture.
"It's like the consistency of a Slurpee, so we just slosh our hands in there and grab a handful," Christensen said.
3) Nature takes it's course as wind and temperatures control the shape of structures.
"After 4 weeks, some of these structures are 20-25 feet tall," Christensen said.
And if the season stays cold enough, they can stretch nearly 50 feet in the air.
"It's really awesome and i mean that literally! I mean, a lot of times you go in and you're just in awe."
Christensen says the popularity frozen has definitely boosted business.
"Kids come up and their like, this is just like in frozen and they're looking for the snowman," he added.
With locations in Utah, Colorado, and New Hampshire, tourists have even come out to take wedding photos and celebrate special occasions.
"It's something that's beautiful that you haven't seen before. I can almost guarantee that," Christensen said.
But when Christensen's not overseeing his cool creations, where does he spend his time? Hawaii.
"I don't want to live in an ice castle anymore than I already do."
