"This is a magical device. You open it and things jump at your face and hit your eyes. As you touch it, you may have an allergic reaction and sneeze, especially if the device is quite old. But... beware. You must hide it. You must hide it carefully. This device was brought to us millions and millions of years ago by the humans."
