We know that Netflix came out with a statement telling people to stop participating in the Birdbox challenge that requires people to try to do things while blindfolded, but that warning wasn't good enough for Mo.
In the movie Birdbox, Sandra Bullock has to avoid looking at a monster by keeping a blindfold on her face, so people have been doing "challenges" to mimic the movie.
So watch Mo ride a tricycle while blindfolded and there are also a few more videos of people doing the challenge included here as well.
