The Stream of Flames is a charm of unknown incantation which allowed the caster to produce a flow of purple fire from the tip of their wand.

Draco Malfoy used this spell sometime in the 1991-1992 or 1992-1993 school year, whilst standing beside a cauldron against a brick wall.

This spell may be related to the fire rope, firestorm, or fire-making spell, or alternatively all three, although none of these theories has been confirmed. It may also, given the colour, be a relation or variation of the Bluebell Flames charm, which was popularly used by Hermione Granger throughout her life.
