If your roommate's alarm is going off and they don't wake up from it, call their phone (only if their alarm is on their phone) this will turn it off. This is great for a time when you want to sleep and their alarm just keeps going off.
This is a great life hack for those who frequently get the hiccups. It may sound strange, but my sister seems to get the hiccups at least once a week, if not more often. This would be great if it works!
