A Swedish children’s TV show that aired a video earlier this year featuring animated dancing genitals has launched a new clip of singing tampons to teach youngsters about menstruation.

The Period Song will air on Friday on the Barnkanalen children’s channel, part of the public service broadcaster SVT. The broadcaster said it hoped the video would help to destigmatise the subject and explain menstruation to children.

One of the channel’s young hosts, Alex Hermansson, sings with teenagers and pulls on the tampons’ strings to make them dance like marionettes before submerging them in a glass of red-coloured water.
