One of the events is “Science Day at the Ballpark.”

“So we’ll be at the Phillies’ game for the science of beer, which is a great new way to way to look at something we all engage in,” explains Steve Snyder, vice-president of exhibits and program development for the Franklin Institute.

Snyder says the ten-day festival covers, in his words, “everything from making boats out of tin foil to the secrets of Jell-O.”

The secrets of Jell-O?!

“Well, there is a lot of science in things that you would never, ever expect,” he says with a laugh.  “One of the things that’s great about a festival like this is that it really lets you explore a bit — how mayonnaise happens (for instance), how you really go from oil and egg white to actually making mayonnaise.”

And don’t forget, there’s a night out with the stars.

“Our skygazing night.  You’ll be able to go out on a street corner, find an astronomer with a telescope, and really explore the universe in a brand new way.”

And this year there is something new: the Philadelphia Science Film Festival, with many of the films making their premiere here in Philadelphia.

“One of the most interesting ones is ‘Man on a Mission,’ ” says Snyder, “and this is the gentleman who spent $30 million of his own money to get into space; how it touches that notion in all of us going beyond to the place that no one else has gone.”

There’s also the science carnival, the science cabaret, science superheroes, the great vaccine debate, and much, much more.

And that’s “Positively Philadelphia!”
