This is a demonstration of an X-ray machine called a fluoroscope. To use it, just "grab" the small wire-frame with your pointer, hold down the button, and move it around. You'll see the X-ray of the hand through this window!

Is it really so surprising that x-rays can go through solid objects? Do you know why some things, like bones or metal, are more resistant to x-rays than skin and muscle? Did you know that light can also penetrate some materials?
