Firework

The Sims
In The Sims: Livin' Large, the Sky Scorcher Fireworks Kit can be bought in Buy mode for §90. It is a rocket on a stand, which Sims can fire for fun. When fired, the rocket will rise into the air, then come back to ground and explode. The rocket can start a fire if it hits something flammable, and will start a fire if it is used indoors.

The Sims 3
Fireworks are an item introduced to The Sims 3 in The Sims 3: World Adventures expansion pack.

Fireworks can be bought at Shang Simla Market for 75 simoleons. Sims light them and watch fireworks displays. These are best viewed from Map View.

A display involving five or more packets of fireworks will result in the Saw Great Fireworks Show moodlet, offering a mood boost of +10 for 16 hours.

Sims watching fireworks will clap and cheer. Sims cannot use fireworks inside a room.

A Sim lighting fireworks in a Graveyard will awake some ghosts and sometimes get Simoleons for entertaining them.
