Chemistry club
The Chemistry club was a club at Canterlot High School dedicated to all things chemistry. They were among the many clubs that Rainbow Dash joined in order to beat Applejack in a competition as to who could join the most clubs. It ended poorly for her, as her concoction ended up blowing up in her face, literally.
