"We were doing some physical challenges, like laying down and rolling over holding a shoe on your foot, from a [physical education] teacher on YouTube earlier. Bad weather outside," she said, per BBC. "She just wanted another one."
The so-called "penny challenge" was one of the many ill-advised dares that began circulating on TikTok over the past year.

Amazon said it had immediately updated its system to fix the "error".
"Customer trust is at the center of everything we do and Alexa is designed to provide accurate, relevant, and helpful information to customers," it said in a statement.
"As soon as we became aware of this error, we took swift action to fix it."

Artificial intelligence expert Gary Marcus told the broadcaster the incident shows how AI systems still lack common sense.
"No current AI is remotely close to understanding the everyday physical or psychological world," he said.
"What we have now is an approximation to intelligence, not the real thing, and as such it will never really be trustworthy. We are going to need some fundamental advances — not just more data — before we can get to AI we can trust."
