Try mixing the elements of chemistry to kick off the holiday weekend at the Chemical Heritage Foundation’s Science Fair, a First Friday event in Old City.

The foundation’s museum will stay open late for First Friday, a monthly open house for art galleries in the Old City Arts District. It will host the science fair from 1 to 8 p.m. to let children and adults embrace the scientific spirit of Benjamin Franklin through chemistry workshops. The fair will have indoor and outdoor demonstrations each hour until 7. Workshops and demonstrations include “Make Your Own ‘Interesting’ Ball” and “The Oscillating Clock Reaction: Experimenting With Chemical Color.” Families can learn how to make fireworks, chemistry sets, and cyanotype sun prints. The event will feature the popular kid-oriented demonstration called the Gummi Bear sacrifice, also known as the Screaming Jelly Baby in Britain, where a Gummi Bear is added to potassium chlorate to demonstrate its powerful energy as the bear makes a screaming noise during the sugar oxidation process. The science fair is appropriate for ages 8 and older. . . .

First Friday at Chemical Heritage Foundation Science Fair, 1 to 8 p.m., 315 Chestnut St. Museum hours are 10 a.m. to 4 p.m. Mondays through Fridays. The museum is open until 8 p.m. on the first Friday of every month and closed on holidays. Admission is free to the museum and fair. Outdoor demonstrations will take place weather permitting.
