The words “chemical” and “heritage” don’t usually get us excited — and let’s face it, the combination is worse. But the Chemical Heritage Foundation, which opened the doors to its 17,000-square-foot museum and conference center in Old City earlier this month, is definitely worth a visit. Ten years in the making, this $20 million project uses contemporary art, history, current events, artifacts and technology to examine science in our everyday, beaker-phobic lives.

“A museum is a visual place, and we really wanted this one to be captivating,” says curator Erin McLeary. “Even if you don’t know what something scientific is, you’ll find it interesting here.” From birth control to computers, explosions to pasteurization, the permanent exhibit conveys the roles science has played — and continues to play — in shaping modernity. The first of the changing exhibits, “Molecules That Matter,” takes a look at 10 organic molecules that have influenced the world, including familiar faces such as nylon, DNA and aspirin. “We’re not as interested in teaching science as much as we are exploring how it occurs in our world,” says McLeary.

If the science doesn’t draw you in, the striking renovation of the First National Bank (built in 1865) is worth a look. The large arching windows let in plenty of natural light — a rarity in the museum world — and the eco-friendly construction included wall tiles and floors made from recycled materials. Then, of course, there are our favorite two words: free admission.

When Visiting: so the museum will be closed from Jan 19 – 23rd for construction. Normal hours are Monday to Friday 10-4. Not exactly conducive for a “night out” but listen up: It won’t take you more than an hour to go through the exhibits, so aim to be there around three o’clock and then march over to Second St, do some shopping and hit up the bars for happy hour! Old City is chock full of great places to go for food and libations. Some PhilaCulturati favorites include the church-turned-bar National Mechanics, a local brewery with a contemporary vibe, Triumph Brew Pub,  and the Khyber the city’s best hipster hangout.
