The general manager of the John Hancock Observatory explains the impetus behind Skating in the Sky and what makes up the rink of "ice."
John Hancock Center officials plan to open that a 94th floor "ice" rink on the observatory this week.
Skaters will have a chance to twirl and twist more than 1,000 feet in the air on world's highest ice skating rink, according to the building's management.
The rink is made of a synthetic substance called "xtraice," which allows the rink and room to be kept at a comfortable temperature -- no Zamboni needed. Kids and adults will be able to lace up their real skates, too.
"This is really a two centimenter-thick synthetic product and on top of it we apply a water-based silicone, which provides the glide," said Daniel Thomas, the observatory's general manager.
Cinderella and Prince Charming from the touring "Disney on Ice presents Princess Classics" will be performing on a similar rink.
The rink will be open January through March. See the concierge on the 94th floor for tickets.
