As many as a dozen children attending a kindergarten in the western Norwegian town of Sola may have sampled some blood that a teacher brought into class for show and tell.

According to Inger Lise Andersen, director of the Dravhaug kindergarten, the unnamed teacher had returned from a visit to the doctor, where she asked a nurse if she could have some of her blood in a vial to take with her to class.

During the children's "sharing time," the teacher reportedly brought out the vial, and poured its contents into a plate for the kids to pass around.

"The children asked if they could touch it and she allowed them," Andersen told Reuters. "Then they asked 'how do we get it off?' so she put her finger in her mouth and the children followed suit."

It's unclear how many of the 12 children in attendance actively participated in the tasting portion of the lesson, but the kindergarten has already sent the blood to be tested for HIV/AIDS and other blood-borne illnesses.

The teacher has since apologized for her actions but was terminated nonetheless.
