Exploratorium Makes Girl, 6, Giggle and Squeal with Delight

My granddaughter owns a short attention span — except when she’s fascinated.

And then the 6-year-old, like most kids her age (or younger), insists on repeating whatever’s grabbed her, again and again and again. Her recent visit to the new Exploratorium is an unequaled for-instance.

She had nearly as much fun as horsing around with her new rescue puppy.

Hannah had been to the old science museum building in the Palace of Fine Arts multiple times, and loved it. But this time her squeals of delight were louder, her giggles more effervescent.

Repeatedly.

Once upon a time she raced from one exhibit to another, testing each for about half a second. But she was only 5 then. Or 4. Or 3 the first time we took her.

Now, she’s exponentially more mature.

Can the word “sophisticated” fit a first-grader? Yes, of course (though I grant a substantial bias in Hannah’s case).

Anyway, this time she lingered at exhibits. And tested each again, again and again.

She didn’t tire until the beginning of our fourth hour.

Like a white-haired roadie, I trailed her as if she were a rock star whose latest single had just gone viral. And I managed to experience much of her hands-on, trial-and-error experimentation from an analogous child’s-eye-view.

I left believing that had I looked close enough, I could have seen her mind expand.

The new Exploratorium, like the old, is an interactive, two-story science museum. But this one’s indoors-outdoors, a 330,000-square-foot facility with three times the space.

It has 40 new exhibits and 560 carryovers, gratifying each of the senses except taste (and that craving might be satisfied at the posh 200-seat buffet-style Seaglass Restaurant or a tiny takeout café, “the seismic joint”).

Because the facility’s bigger, it doesn’t feel cramped or crowded. And it seems a bit less noisy (as well as somewhat less exciting).

But Hannah didn’t think about any of that.

She was too busy running back and forth between two displays — “Self-Excluding Mirror,” which reproduced images but somehow made the person in the center disappear, and “Self-Centered Mirror,” which replicated the viewer over and over.

Before that, near the entrance, she’d became entranced with “A Drop to Drink,” featuring a miniature hand she could manipulate robotically to fill a miniature cup with a lone drop of water, and “Black Sand,” an exhibit that showcased countless metallic pieces that stuck together magnetically. A few times during our visit she returned to both stations.

Hannah enjoyed exhibits carried over from the old building.

One favorite — where images and colors changed when we waved our arms, kicked out our legs and wiggled our torsos. Another was a screen crammed with pins that made different hand shapes and designs as she moved her fingers underneath.

Another echo came as Scott Weaver guided ping-pong balls through his panoramic view of San Francisco and vicinity made from “105,387 and a half toothpicks.” We’d seen it before, at the Marin County Fair, but loved it still.

His art-piece only took 37 years to finish.

Hannah was also taken with “Tidal Memory,” its 24 columns of water representing 24 hours of tide data.

I, meanwhile, enjoyed playing “The Visible Pinball Machine,” which showed the machine’s innards. And all of us marveled at “Gyroid,” an outdoor climbing maze Hannah crawled through and atop while we watched.

Leaving, Hannah gleefully said she liked running into and out of an “orange and white spinning circus-tent thing,” spinning a plastic ball on a column of air, and changing the course of a simulated tornado.

It’s truly impossible to even mention all we experienced, much less what we didn’t do (like check out the second floor and its observation center).

But we did recognize the Exploratorium features displays for virtually every age, ranging from some aimed at preschoolers to some so technical a doctorate in an esoteric scientific endeavor might help.

I think that translates, in effect, into something for everyone.

All that’s required is sufficient time.

Oh, well, there’s always next time. Or the time after that. Or the one after that. Or…
