For the past two days, I have been suffering from vertigo, trying to get my body to remember which way is up. What causes vertigo?

Brain Freeze

Anonymous: 
This week's experiment comes from a question that I got from a list member. As I researched the question, it was even more interesting than I expected. It also seemed like a good excuse to eat lots of ice cream. First off, I don't recommend giving yourself a headache. If you have ever had an ice cream headache, you already know what it feels like. If you have not, you probably won't, as only about 30% of people get this kind of headache. They usually happen on hot days, when you quickly eat lots of ice cream or other very cold things. Suddenly you feel a strong pain in your head, which many people call brain freeze.

The Place You Can't See

Anonymous: 
This week's experiment is an old classic, but it is one that always amazes me. Each of your eye's has a blind spot. A small area where you cannot see. What amazes me is not that there is an area that you can't see, but that you can't see the "hole" in your vision. Instead, your brain fills in the space, so that you don't notice it.

One Eye or Two

Anonymous: 
I thought this week we would do something on judging distances. If you look at the faces of different animals, you will find that their eyes are placed differently. Some have both eyes in the front of their face, like ours. Others have their eyes on the sides of their heads. Why? We can do an experiment to learn at least one reason for this.

What is it really like to look at the world through rose colored glasses? Not nearly as strange as when you finally take them off!

Here's a llama. There's a llama. If you have ever heard the , Llama Song , you are probably familiar with having a song stuck in your head that just won't go away. What is the scientific name for this?

Flickering Fingers

Anonymous: 
For this week's experiment, we are going to watch our fingers wiggle. Doesn't that sound like fun? OK, I admit that I am easily amused, but there is more to this experiment than just moving your finger. We are going to investigate part of how a television works at the same time.

Make Your Own Stereogram

Anonymous: 
Have you ever seen a random dot stereogram? You see them on posters, cards, calendars, etc? It can be a random pattern of dots or a repeated pattern of just about anything, and if you stare at it in just the right way you suddenly see a 3 dimensional image sticking out of the page. Have you ever wondered how they are made? Lets take a look.
