The Rice Throw
We were actually a little cagey about putting this one on the list. It's fun, everyone gets to participate, and pelting the bride and groom is a good way to let off some steam if the salmon at dinner was dry or the registry was too ambitious.
Here's the problem: For years, there's been an urban legend circulating that uncooked rice expands in birds' stomachs and makes them explode like little feathery firecrackers. Is it true? No, but people do believe it, which means dirty looks from passersby and the possibility of flower girls in tears. Not to mention everyone having to pick grains of rice out of their hair for the rest of the day.
