Escrit i vídeo fet per alumne de 1r ESO “cançó de Katy Perry”

Hello, my name is Sergio Zvir, I go to 1st Eso E and I am a fan of the Floss or the Backpack kid Dance.
When I saw the YouTube Rewind 2017 I saw the Backpack kid dancing and I started to practice his dance because it was really cool.
I practiced one day and every day I got better and sometimes I can teach my friends to do it with me. But when I saw all the videos of Backpack kid I see he can do a cool dance with all the songs including the Christmas songs.
