How to give yourself temporary night vision!!

Ok, coolest thing ever right here. It's really simple. Take one hand and hold it over one of your eyes (keep your eye closed as well) for at least 20 minutes. After the 20 minutes is up, shut off all of the lights so that it is very difficult to see with your eye that is not covered. Then, uncover your eye. Too your surprise you will be able to see everything clearly!

This is awsome, and everyone should try. The reason this works is that the rods in your eye that allow for low light vision take 20 minutes to adjust to darkness levels. When adjusted to the no light condition of your hand, the available light condition of a dark room becomes clear.
Note: Rods only see in black and white, so that is how you will see in the dark, but some color might be visible.

Don't believe me eh? Give it a try. And for your information, I learned the trick in a Psychology class.
