We bought a few boxes of sparklers for the New Year.
Tips
memory
Literally "fairy wand" - 仙女 (fairy/celestial maiden) + 棒 (stick). The shower of sparks looks like the trail from a magic wand.
register
The slang sense (vibrator) is internet/youth-speak. In a casual conversation about Lunar New Year (春节), it just means sparkler - context disambiguates clearly.
