This year’s Atlanta Science Festival (ASF) will conclude this weekend with “the city’s biggest science party of all time,” the Exploration Expo, ASF announced in a press release. The event will take place between 11 a.m.-4 p.m. on Saturday, March 24 at Piedmont Park.

Featuring more than 100 hands-on interactive science booths, live science demos and shows from local organizations, universities and companies, the expo is free and will take place rain or shine.

“If the Atlanta Science Festival has a big bang, it would be the Exploration Expo,” Jordan Rose, ASF co-founder and co-director, said. “We’re here to showcase and celebrate the science that’s happening in Atlanta. Where else can you experience everything from touching a human brain to driving an undersea robot?”

The expo will feature seven different “zones” where attendees can explore all different branches of science, which offer activities from measuring Atlanta’s pollen count to driving underwater robots to writing science haikus.

There will also be plenty of food options, with vendors include King of Pops, South of Philly, Choice Concessions, Jim ’N Nick’s Bar-B-Q, Repicci’s Italian Ice & Gelato, and Kona Ice. Complimentary bottled water and KIND Bars will be available at stations throughout the Expo.
