Sarah sat down on the floor of her room and sighed after a long day at Uni. She'd decided to take her equipment - namely, a canister of liquid nitrogen - home due to a viral internet fad wherein young girls would use stolen canisters to freeze themselves solid while live-streaming it. "What are you doing with my stuff?" she nagged at her boyfriend, who by now had noticed the hefty load in her bag and was investigating. "Nothin', what's this?" He held up the canister "Liquid nitrogen?"
"Yeah, be super careful wi-"
At that very moment, the canister detached from the cap and fell out of her boyfriend's grasp, falling forward and instantly freezing the upper half of Sarah's body.
"Ohhhh shiiit."
Sarah's boyfriend, dull as he was, tried asking the internet for help instead of dialing 911; using his phone he recorded Sarah's half-frozen form and uploaded it in a call for aid, only for the video to garner thousands of likes and views instead, making Sarah the first accidental victim of the Liquid Nitrogen Challenge.
