A pinata at a fiesta is great fun, but can be very dangerous if the hitter is still swinging when the pinata is broken and the kids rush in. I organize this activity by instructing the kids that no one can move until I blow a whistle, or yell a word really loud like "ARRIBA" meaning it's safe to run.
We are having a Cinco de Mayo party at school on Tuesday and were having a taco bar, lemon-lime drinks, and crafts for the kids. The kids will love to make their own tacos.
