Educator Guide: Make a Möbius Strip and A Sweaty Plant Adaptation

A surprise twist brings a Möbius strip mystery to an end. So simple in structure yet so perplexing a puzzle, the Möbius strip's twisted loop grants some unexpected turns. Learn about what a Möbius strip is by constructing them from paper and tape, then use these deceptively simple structures to challenge intuitive judgments about their construction ratio limits.
