Debby Heerkens, a biology teacher in the Netherlands, came up with a interesting way to educate her students. She stood up on her desk and stripped off her clothes to reveal a full suit of spandex illustrated with accurate muscles and organs. Below each layer was another part of the body.
Heerkens came up with the idea when she saw someone walking around town with similar leggings. After finding them online, she made sure that it was ok with the school’s director and then brought them in to class.
