You can buy fireworks and sparklers from the merchandise stalls during the festivals that take place in San Myshuno. You can also order fireworks on the PC if you don’t want to attend the festivals.
Alternatively, you can also use cheats to get your hands on some fireworks. Press Ctrl, Shift, and C, type in testingcheats true and hit Enter.
Then type in bb.showhiddenobjects to show hidden objects. Type debug in the search field and use the Debug menu to find your fireworks.
Three types of fireworks are available in the game: Roman Candle, Mortar, and Spark Fountain.
Roman Candle fireworks cost 15-20 Simoleons and contain a series of colorful streaks that will light up the sky.
Mortar fireworks cost 35-50 Simoleons and contain a single mortar shot.
Spark Fountain fireworks are the most expensive and spectacular fireworks that you can buy in The Sims 4. One pack of Spark Fountain fireworks costs 50 Simoleons.
Your Sim can set these fireworks off and enjoy a cascading fountain of sparks.
Shooting fireworks indoors will start a fire
Shooting fireworks indoors will cause a major fire. Don’t do that unless you want to scare or kill your Sims.
Sims will always try to put out the fire even if autonomy is off. If there is more than one Sim in the area, and one of them has been engulfed in flames, the others will try to extinguish the fire.
Happy Simming!
