Dr. Filibuster's Fabulous Wet-Start, No-Heat Fireworks

• Type: Magical Item (Fireworks)
• Owners: Fred Weasley, George Weasley
• Maker: Dr. Filibuster (presumed)

The specific appearance of these fireworks is not described in the novels. They are sold as a product, likely pre-packaged, and are available for purchase in places like Diagon Alley. Their fantastical name suggests they are a high-quality and impressive product line designed for amusement.

The defining characteristic of these fireworks is their unique ignition method, as advertised in their name: “Wet-Start, No-Heat.” This indicates they do not require a flame or any conventional heat source to be set off. It is likely they can be activated with a simple tap of a wand or a specific spell. Their primary use is for entertainment and, in the case of their known users, creating diversions and pranks. When detonated, a single firework was shown to be quite powerful, producing a series of “loud, canary-yellow stars” that shot out of one end and ricocheted off the walls and ceiling of a Hogwarts corridor for a sustained period.

The broader history of this product line is unknown. The only known purchase of these fireworks occurs in the summer of 1992, when Fred and George spend their Galleons on them in Diagon Alley before starting their fourth year at Hogwarts.

These fireworks are featured in Harry Potter and the Chamber of Secrets. They serve as an early example of the Weasley twins' affinity for high-quality magical joke and prank items, foreshadowing their future careers as the successful proprietors of Weasleys' Wizarding Wheezes. During the 1992-1993 school year, Fred and George use one of Dr. Filibuster's fireworks to create a diversion to help Harry Potter. When Harry, covered in mud after a Gryffindor Quidditch practice, is about to be caught by Argus Filch, the twins set off a firework in a nearby corridor. The ensuing chaos of loud bangs and ricocheting sparks distracts Filch long enough for Harry to sneak past, enabling him to reach Moaning Myrtle's bathroom to continue his investigation into the Chamber of Secrets.

The term “filibuster” in the Muggle world refers to a political procedure where one or more members of a legislative body engage in prolonged debate or other obstructive actions to delay or entirely prevent a vote on a proposal. This reflects the function of the fireworks in the story, which is to create a lengthy and noisy distraction to obstruct Argus Filch from performing his duties.

This item does not appear in the film adaptation of Harry Potter and the Chamber of Secrets. The character of Dr. Filibuster is never seen or mentioned outside of this product's name, suggesting it is simply a brand.
