Ski Ballet was a graceful freestyle skiing discipline from the late 1960s to 2000s. Choreographed to music, performers flip, roll, spin, jump and glide down a gentle ski slope. The Winter Olympics featured ski ballet, now known as acroski, as a demonstration sport in the 1988 Games in Calgary, Canada, and the 1992 Games in Albertville, France.

Speed Skiing is the fasted non-motorized sport on Earth. Pointing their skiers straight downhill, skiers can gain speeds upwards of 150mph. For context, this is faster than a skydivers terminal velocity of 118mph due to wind resistance. This sport debuted as a demonstration sport in the Albertville, France Olympics in 1992. This sport lost its Olympic momentum when a skier was killed hitting a groomer in practice.
Bandy is where hockey meets soccer. Teams of 11 players on ice use sticks to hit a ball around a rink the size of a soccer field.
