Did you know that sparklers can burn under water? This is because they contain an oxidizer (usualy Potassium nitrate or Potassium perchlorate) as a oxygen source instead of getting oxygen from the air. As a result, they are able to burn even when they are placed in an environment where oxygen is absent as Myles shows.
