Point it at the dust, pull the trigger, and WHOOSH. The dust is GONE. (don't know where, but the dust is gone) I don't know how they get ALL THAT AIR in an 8 oz. container, but they do. I dusted the inside of my computer, I dusted the outside. Then I dusted the books. Then I used it to scare the cats! What fun! An ENDLESS supply of dusting air. Right now I'm using it to turn pages on the book I'm reading. Next page, psst, next page, psst. Works great, HEY, what 's happening! no more air! piece of junk...Oh wait, TWO CANS IN A PACK!!
