Yeah so if a nerdy guy snaps the bracelet, do you think he gets anything? They interviewed some kids about this and they all said that " snapping a bracelet is not going to make us want to have sex. "
But since avoiding evil is a good idea, I would tell kids not to wear them. I would also tell them to buy bracelets that don't break. Then when the guy tries, teach the girl to drop kick the bastage and yell, "no I will not make out with you!"
