I can see them distributing the setup to havenworlders of higher numbers, programming the "fireworks" to an acceptable amount of "surprise and noise" according to the havenworlder in question. And the best part is, since they're mini-drones and not balls of fire, they can be programmed to return to the launcher and balls and be recharge. Basically, a reusable, rechargable, firework set. LOL Though I gotta ask, why would the human be laughing his arse off? I'd think he'd think it was cool to have a firework that he could recharge and reuse, and program to be human-levels of noisy and bright if he wanted them to be?
