Nerds take over the city for the Philadelphia Science Festival

This year’s Philadelphia Science Festival is starting out with a bang tonight at the fest’s Science Carnival After Hours at the Franklin Institute.

When we say bang, we specifically mean the reaction of liquid nitrogen fused with a cracker in your mouth. It’s an explosion — perfectly safe, we hear.

“The smoke goes out of your mouth and you look like a fire-breathing dragon,” says Liz Kelley of the Franklin Institute.

Fire-breathing dragons over drinks in a casual setting is a way to get those who are not so scientifically inclined engaged in science.

“Liquid nitrogen isn’t something you normally have access to,” Kelley says. “It’s a good way to experience science in a new novel way.”

Such is the mission of the fourth annual Philly Science Fest. There are more than 100 events around the city, tonight through May 3, in austere locales like the Franklin Institute and decidedly non-traditional places, like the Paine’s Skatepark, where the science of skateboarding and barefoot running will be discussed.

Most of the events are kid-friendly —such as the Mess Fest on April 27, where Alka-Seltzer rockets will be launched — but there’s a good helping of adult-themed stuff, too: The “Nerd Nite Brunch: Body vs. Booze” on April 27; “Phanatics: Philadelphia’s Love/Hate Relationship with Sports” on April 28; and “Love, Lust and Loathing: The Science Behind Our Strongest Emotions” on April 30, to highlight a few.

“‘Love, Lust and Loathing’ is going to be really fun,” says Gerri Trooskin, the science festival director at the Franklin Institute. “A talk will be called ‘Does Size Matter’ and it’s the role of vocal chords and the role they play in human attraction.”

Like the old songs says, it’s all about how you call your lover boy.

Drawing a crowd

More then 90,000 people attended festival events last year, including the wrap-up Science Carnival on the Parkway, which drew 30,000, Trooskin says. This year’s carnival on May 3 will feature 175 exhibitors blinding you with science, plus live entertainment and food trucks.

“We want to make sure that this is not only fun and interactive and entertaining, but it’s also rich in content,” says Trooskin of the fest. “That’s what people are drawn to.”

Event prices range from free to $40. Get all the details at
