* For the food: "बिसकुट" (bis-koot) is the most common word for crackers.
* For fireworks: "पटाखे" (patakha) is the word for fireworks.
So, you would say:
* "मुझे बिसकुट पसंद हैं।" (mujhe bis-koot pasand hain) - "I like crackers." (referring to the food)
* "दीपावली में पटाखे बहुत होते हैं।" (Dipawali mein patakha bahut hote hain) - "There are a lot of crackers during Diwali." (referring to fireworks)
