Hmm, maybe Flocking Fireworks covered this.

A 3d matrix of firework drones acting as a screen.

You could also do this with balloons made out of a fireproof material.

Excellent, but what is a firework drone?

<sotto voce>

It's an essential component of a set of Moriarty & McGonagall's Patent Exploding Bagpipes ... possibly the best (or at any rate, least worst) bagpipes ever made; they produce a brief but spectacularly colourful display of pyrotechnics before exploding with cataclysmic violence, destroying both themselves and the indiviudual attempting to play them.

As such, they are revered by musicians everywhere.

The ingenious initiation mechanism, combining an air-pressure operated safety switch in the mouthpiece and a flow-sensing arming mechanism in the chanter, ensures that they can be safely handled under all circumstances, right up to the moment a wilful and malicious attempt is made to operate them in the "correct" manner by one accustomed to the weapon.

It is best that their existence does not enjoy undue publicity*, as the surreptitious substitution of a set of these pipes for a normal set is seen by law enforcement everywhere as the most prompt, cost- effective and satisfying way of dealing once and for all with repeat offenders.

*Up to now, a Gentleman's Agreement between the authorities involved have explained away the "Spontaneous Bagpipe(r) Explosion" phenomenon by blaming it on "Whisky vapour detonation in the bag", which everyone sems happy to quietly accept.

There's no need to shout. And you need to work on your spelling.
