Yana Welinder(@yanabana):Ever tried solving a Rubik’s Cube in seconds? My 9-year-old went down the YouTube rabbit hole of learning speedcubing. Today, as part of @AlphaSchool’s Founder Weekend, he turned everything he learned into a teaching tool and community for other cubers. He’d love your feedback. Give it a try!
