The only thing that makes going to the movies better is watching your favorite movie in 3D! But how does wearing glasses make movie characters pop out of the screen? And why don’t all glasses do this? This experiment will help you understand how polarization makes this all possible.
Have you ever wondered how a mirror shows your reflection? Or how when you look at an angle, you can see objects that aren’t directly in front of the mirror? This activity will help you understand both.
Rainbows can be seen in many places besides the sky. Maybe you’ve seen them in your sprinklers or reflected off of oil. This experiment explains why that is.

Wanna see things up close? This activity helps kids make their very own magnifying glass!
In this activity we'll examine this strange phenomenon and how we can experience it throughout nature. We'll also examine what thin slits do to light and how this phenomenon is similar to that of bubbles and oil slicks.
This activity explores capillary action - how water moves up paper - and chromatography - how different elements of the ink are carried along at different rates, allowing you to see that black ink is actually made up of many different colors.
A red object appears red because it reflects mostly red light back to your eyes. All the other colors of visible light are absorbed into the object. But what can make a green gumball black?
