Which of the following might cause glass to break in a freezer? Putting thin glass in the freezer
Setting the temperature too low
Failing to allow room for expansion
Freezing any liquid in a glass container

Answer is failing to allow room for expansion. Food expands when you freeze it, and the only place it has to go is the space you leave at the top. In order to prevent glass jars from breaking in the freezer, you need to leave plenty of room at the top.

10/10 recommend bring pads/tampons with you no matter what. im 16 & i’ve had mine since i was 12 and they’re still it regular, but id suggest using the glow app, many women use it for fertility reasons but i use mine specifically for the period tracking portion and it guesses when your next period will most likely be for the next two months. i dont believe theres any way to delay your period, so id say hope for the best but make sure to bring all of your stuff just incase. have a good cruise!
