The top five things to do this weekend

The Seaport Village Busker Festival returns on Saturday and Sunday.

Spring is officially here, and so begins the season of outdoor activities. Here’s what you’ll find going on this weekend:

Seaport Village Busker Festival

From swallowing swords to juggling on unicycles, buskers are entertaining street performers. This weekend, Seaport Village presents a dozen buskers at the sixth annual Busker Festival. Past performers include Murrugun the Mystic, who not only eats fire but lies on a bed of nails, and Bobby Besmehn, a juggler and unicyclist who has been featured on David Letterman’s show.

San Diego Festival of Science Expo Day

Everyone from cynical high schoolers to wide-eyed toddlers will be able to mix chemicals to create bubbles and explosions and hold insects in their hands. There will also be hundreds of booths set up throughout Petco Park by high schools, colleges and universities, as well as other San Diego nature- and science-related organizations.

Details: San Diego Festival of Science and Engineering Expo Day, 10 a.m. to 5 p.m. Saturday. Petco Park, downtown.

Lady Antebellum, with Darius Rucker and Thompson Square

Lady Antebellum has made a pop-country blend that is more pop than country, to the clear benefit of the trio’s multimillion-and-growing record sales. As a result, the audience for Lady Antebellum includes a large percentage of fans who don’t typically listen to country music. (George Varga)

The concert features music from the Marianas, Polynesia and Micronesia. (Jenny Lee)
