Sparklers are literally all you need. They fuck shit up worse then M80's if you know what you're doing.
you cant have fun without party poppers, just ride around a neighborhood and slow down when someone is walking and just pop it on them, its funny... until you see cops coming down the street... luckily me and my friends never got caught.
after the day of New year in sweden the firecrackers are illegal to use -.- so the only day u can use firecrackers is New Years day. in other places? is it just free to use firecrackers which ever day? XD
