Whistling Rockets

The category splits mainly on what happens during the climb and what happens at the burst, and Whistling Rocket is deliberately built for both halves. Colour Rockets climb silently and burst into coloured sparks with no ascent sound at all, visual only. Sound Rockets do the opposite, climbing to a loud aerial bang with no colour and no whistle. Whistling Rocket sits between the two: you hear it rise, then watch it burst, a different experience from either a silent climb or a straight bang.

Lunik Rockets take the whistle-and-colour combination Whistling Rocket runs and add a sound burst on top, so if colour plus whistle plus bang together is the goal, Lunik is the fuller version of the same idea. Two-Sound Rocket, by contrast, drops the whistle and colour entirely in favour of two separate reports, and carries the highest noise rating in the range as a result, a genuinely different pick from Whistling Rocket rather than a louder version of it.

Format variants complete the picture: Bullet Rocket for a fast, steep climb; Mini Rocket for a smaller charge and shorter flight where space is tight; and Sky Rocket with Tail for a visible spark trail on ascent ahead of its own colour burst, a visual-ascent alternative to Whistling Rocket's audio one.

The whistle gives you an audio cue that the rocket is climbing. Treat it as the signal to stay well clear of the launch point, not to lean in for a better view.

Set up on open ground, clear of vehicles, dry leaves and the festival lamps, with water and dry sand beside you before the first light. Use an incense stick at arm's length, one cracker at a time, and leave any dud alone, soak it rather than relight it. Children hold sparklers only, always supervised, in cotton clothes and closed shoes.
