Light and Eye Experiment

My junior year of college, I took a class called Color and Light. This class was talked up to me by friends of mine on the rowing team, and I took it mostly because I heard about this experiment the teacher runs with the class. Although I could've done the experiment on my own (and I suggest you should try it), I took the class anyway.

THE EXPERIMENT

We walked into class one day and the teacher handed us each a bunch of cotton balls and bandanas. The windows were covered with blankets. He tells us to hold the cotton balls over one eye, and strap them to your head with the bandana. The other eye is left open and able to see. He then lectured as normal for 30 minutes. With about 10 minutes left in class, he turned off the lights in the room and had us remove the blindfolds. The eye that had been left open was struggling to see, while the other eye, now dark-adjusted, saw everything. It was a crazy feeling.

Try it yourself!
