is frying food considered ochel nefesh on yom tov, despite not being the traditional method to cook? Does it make a difference if it’s air frying or oil frying?

Is there a mitzvah of simchah on the day of kiddushin, or only on nissuin?

Although some (I believe minority although minor be wrong ) of the poskim are machmir in Halacha with prohibiting opening regular plastic bottles due to make B’patish, do they all permit opening a glass bottle since the cap isn’t screwed off but popped off?
