All Eyes on Me
Situate yourself at just the right place in space in front of this parabolic mirror array and you’ll see dozens of your own eyeballs peering back at you.
Anti-Gravity Mirror
Here’s an exhibit where watching is at least half the fun. You can create any number of gravity-defying illusions that will amaze you and your friends: Levitate, fly, swim though the air, grow limbs (and dissolve them), crawl straight up the wall like a lizard—the sky’s the limit.
Archimedes
Archimedes is comprised of two 8-foot diameter dish-like chairs placed 80 feet apart. Each dish’s parabolic curve collects and focuses sound waves and reflects them to participants seated within them. Even whispers uttered from one dish can be clearly heard by the surprised listener seated in the opposite dish.
Where: Plaza
Aurora
A reflector stretches light from colored tiles into long bright ribbons.
Bright Black
At this exhibit, find out how subjective brightness can be as you struggle—and fail—to correctly decide whether the squares you see are black or white.
Christmas Tree Balls
There are captivating reflections in a box of ornaments.
Disappearing Glass Rods
When light passes from one clear medium into another, it (usually) bends—a phenomenon called refraction. Distortions caused by refraction are part of why you can see objects that are clear.
Where: Crossroads: Getting Started
Echo Tube
Make a sound into the echo tube and listen for it to reflect back from the far end. You’ll hear a half-second delay, and strange distortions created by the journey.
Where: Gallery 5: Outdoor Exhibits
Echo Tubes
Experiment with echoes with these three long tubes. Why does a clap come back as a ping? What does it take to make a good echo?
