That is beyond retarded...and a school is supposed to instruct kids in the truthful ways of life? Spraying oil does NOT eliminate aromatic odor molecules. All it does is dilute their presence. In addition, all of these essential oils are from plants, which many people are randomly allergic or inflamed by. Essential oils are for a home. Spraying essential oils into public airspace is such a dick move. Sorry about your kid, sucks when people spray biologically active drugs into the air that other people have to breathe.
