"Houdini" is a large, 300-shot compound firework from Brothers Pyrotechnics, known for its fanned effects and mix of loud and quiet displays, including traditional bursts, long-tailed comets, and a finale of silver strobes and crackles.
Compound fireworks are a way to get a long-lasting display from multiple barrages joined together, and Houdini is described as having a choreography of effects and a duration of about 90 seconds.
