That's an easy one for me, particularly b/c we are Spanish and we have loads of superstitions. Let's start with New Year's Eve
1. Eat 12 grapes to guarantee food on the table all year long
2. Gather water all day long, and at midnight throw the water out the window/door - purification
3. Throw four pennies at midnight and make a wish for each of "the four lucks": money, romance, health, fate
In the South (Alabama) we make a meal in which the ingredients are symbols: Black Eyed peas for luck, pork skin or pork for health/food on the table, collard greens for money
Other Spanish superstitions I can tell you of are:
4. Doing the cross sign each time we pass a cemetery to bless the gone
5. Doing the cross sign if we happen to hear the voice of a loved one (dead or alive) when they aren't present, for they may need us from wherever they are.
6. Saying "blessings" instead of "hello" (or both) when we call our loved ones.
7. Not keeping objects that come from the ocean (respect)
8. Naming a child after the Saint to which the day is dedicated
9. Of course, beware of broken mirrors.
10. If you are pregnant, stare at nice pictures of healthy babies all the time so your kids can adopt the traits.
