Today is Halloween, and fans of the spooky and candy-centric will have their pick of events around the city. Trick-or-treaters can drop by a block party, while the science-minded can learn about the neurochemistry behind our fears or the art of carving a pumpkin underwater.

The weekend brings still more trick-or-treating, along with a celebration of rescue animals, a ballpark science festival, and an art event focused on reducing plastic usage.

Here's your guide to getting out and having fun in San Francisco this weekend.

Treats for kids with food allergies will be available as well.

When: Thursday, October 31, 5 p.m.

Where: Playland at 43rd Avenue, 1360 43rd Ave.

This annual three-day art show, hosted by the Surfrider Foundation, aims to raise awareness about pollution and celebrate the ocean. Visitors can enjoy the work of three dozen internationally recognized artists (curated by Lance Fung of Fung Collaboratives), as well as the creations of hundreds of Bay Area students.

This year's event is dedicated to "Debunking the Recycling Myth," by encouraging attendees to reduce plastic use instead of relying on the imperfect recycling system that leaves millions of pounds of plastic in the world's oceans. Each day's event will feature different bonus aspects, from local beer and snacks on Friday to live music on Sunday.

When: Friday, November 1, 6-10 p.m.; Saturday, November 2, 10 a.m.-5 p.m., Sunday, November 3, 10 a.m.-4 p.m.
