My son's friend brought some "Dust Remover" to our home, and showed him how to use it for a quick buzz..I caught them and they proceeded to tell me It was compressed air and could not hurt them..all the kids are using this stuff at school....My 14 year old has been a good kid.advANCED classes, straight A's, kind, and extremely talented. We had a huge argument over this, and I wanted to know the facts. Is this stuff just compressed air...what harm can it do...and what can I do about this.
