Debby Heerkens, a science teacher at Groene Hart Rijnwoude School in Hazerswoude Dorp, Netherlands, shocked her students when she started to undress atop her table during class.

Underneath her clothes, she was wearing a skin-tight suit that is printed with details of the human muscular system. The stunt was the teacher's attempt of a more creative approach in teaching the anatomy of the human body.

"At first they were a little bit in shock because they thought 'the teacher is taking off her clothes,' until, they saw what was underneath," Heerkens said, according to CNN.

Heerkens was wearing multiple layers of similar suits, also showing off the skeletal structure and the internal organs, the New York Daily News reported.

She got the idea after seeing someone wearing leggings that had the same design. She bought a pair online and took it to class, after of course running the idea past the school director, The Huffington Post Canada reported.

A video of the lesson was posted on Facebook and has gained more than 60,000 views. Some commented on the brilliance of the teacher, and others were inspired by her creativity.

Heerkens has been teaching for seven years and has always been creative in looking for ways to keep her students engaged in her lessons. However, this was the first time that she used a costume to teach a lesson, which she believes got positive results.
