Vortex

Tired of the usual bang, crackle, repeat? Vortex shakes the routine right up.

It's one of the quirkiest cakes in the Evo Fireworks range, built around a three-stage ghost whistle. Each silver comet spirals into the sky with a high-pitched screech that stutters, stopping and starting three times before it vanishes. Thirty-six shots of it, and there's nothing else in the garden that sounds like it.

Rated F2, a garden firework: keep spectators at least 8 metres back for safety.
