How do you use a curling wand?

You just use it kind of like a regular curling iron. You wrap your hair around it. I like them because they don't get the tips of your hair hot and that is good for split ends. See related links for a video tutorial.
Use rollers and or rods. You can shampoo your hair and after conditioning, add leave in or mousse and apply your rods or rollers in sections. Once dry take the rollers and or rods out of your hair and it will be curled.
