I don't use the "On The Rise" category on What's Trending very often, mostly because of the old what-goes-up-must-come-down rule of physics, which also applies to online content. A video which is hugely popular now will not be part of the national discourse in a few months time.
I feel confident with my decision, however, to include "Fishing With Fireworks" in this category for two reasons. One: Fireworks nearly always explode and quite literally "rise." Into the sky when they explode. Two: Fishing with fireworks will, with any luck, become the Swedish version of the Ice Bucket Challenge, a truly "on the rise" trend that will remain in the forethought of our minds and continue to raise money for important causes well into next year.
Endnote: Please do not do this. You'll probably get hurt. I mean, Jesus!
