This will absolutely blow your mind. Teachers if you have a computer in your classroom show your science classes this video. I promise even the most hard core haters of learning will be amazed at something called the McGurk effect. You have heard the phrase " I see what you are saying"?

In reality we know you can't do that, or can you? What we see actually tells our brains what we hear. I guess that's why it's a good thing we don't have pictures on the radio because we'd all really be confused wouldn't we? I still maintain this is a very cool lesson for kids to see and you can try it our around the office. It beats having to hear yourself working doesn't it?
