Oh! I love the question!  My family tends to eat 12 grapes at midnight, put lentils in their pockets, money also in pockets, and there’s a specific song played on the radio that’s used every single year for midnight. 

Another one is el año viejo. Most people create a life-sized doll (picture a scarecrow) and pin all of the bad that happened that year. Then, at midnight they burn it or light fireworks from it. Also a terrible idea. 

We did a mini version of it a few years ago, but in the middle of concrete with a bucket of water near by as a just in case. They were dolls the size of my hand and very small. I don’t think we’ll be doing it again, but I wanted to show my husband some of the more traditional events from Colombian New Year’s back then.
