Grab your plastic pail and shovel and head down to Revere Beach for the 9th Annual Revere Beach Sand Sculpting Festival. Watch as master sand sculptors from around the world carefully craft a whole lot more than your typical drip castle, and vote for your favorite. The winners will be announced at Saturday night’s awards ceremony, with fireworks to follow. There will be live music and entertainment — including free, hour-long sand sculpting lessons for kids 12 and younger — now through Sunday evening. For a schedule of events, click here. Beach bullies note: Knocking down the sand sculptures isn’t permitted.
