Fireworks
noun
The flower fire... what looks like flowers on fire? That would be fireworks. Totally makes sense, right?
はなび
The readings for the kanji that make this word are the kun'yomi readings, where fire's ひ changes to び. You already learned the kun'yomi reading for 花 when you learned the kanji, so it's only a matter of remembering to use the kun'yomi for 火. If you do, you should be able to read this word.

川でバーベキューと花火したいなぁ。

今日の花火は中止だってさ。
