'Snowball' by MrTomHol.
Conceptual story goes like this:
Once upon the time, well known Country used 'Q974' [winter edition] to organize first in the World portable winter event, named as 'Snowball'.
Organizations responsible for joyful winter feast invited astonishing count of Winter sports Stars. Unbelievable count of sponsors made it possible by participation. Happy spectators at the location and massive amount of fans around the World via live coverages, all together enjoyed winter games championships.
In the result, winners collected many 'snowball medals' with huge prizes. Sports Champs competed in Snowboarding; Ice Hockey & snow Bandy; Ski jumps; Ice Speedway; Ski runs; Snowmobiles races; Artificial ice fishing; Electric sleigh races; Snow Golf; Ice climbing; Electric Car's snow rally; Winter Triathlon and many other winter sports, including new and very fresh categories.
Because the event was planned during the period of New Year, at the same location took place various of snow parties - including spectacular New Year's Party.
After approximately month of Winter Games and great events with Global super stars, whole object magically disappeared.
In other words, object appeared unexpectedly like a Winter, and vanished like a snow during hot day. It was the first 'Snowball'.
The End.
Naturally we can debate, it is just a pure cold sci-fi, or maybe
it is...
