Skating rink planned on 94th floor
Ice skating in Chicago in January is nothing new - but doing it on the 94th floor of a skyscraper certainly is.
Officials at the 100-storey John Hancock Centre are installing a rink that will allow visitors to skate at 1,000 feet.
About 20 people at a time will be able to skate on the 1,000sq ft rink, which will be open from January to March.
But the rink won't actually be made of ice. It will be made of a synthetic material that creates a hard, plastic floor with a slick silicone glaze.
Installing the rink is an attempt to attract more visitors to the building during a normally slow time of year. The 94th floor also has an open-air skywalk and a cafe.
The grand opening is scheduled for January 1.
