*sigh* 1.  The bottom two of the bottom picture are my responces in between the bottom three of the top picture.  2.  READ THE VEY LAST TEXT ON THE SECOND PICUTURE!

Oh and I got this light that turns on and off by hitting the bottom of it.

List of things that work with it:

My wrist

My forehead

My elbow

Hard surfaces(walls, floors, chairs, etc.)

My knee

My foot

My knuckle bone

The list goes on for a long time...
