Weasley's Wild-fire Whiz-bangs
Unstoppable fireworks that violently explode when hit by a stunning spell and multiply by ten at any attempt to vanish them. These include a shocking pink-wheel, fire-breathing dragons, sparklers that spell out profanity, rockets with long tails of silver stars, and standard firecrackers. When any two types collide, they make new effects. Include Basic Blaze Box and Deflagration Deluxe.
