So I don't have compressed air and I'm wanting to dust my medium dusty computer, is it okay to eat bread so that my mouth is dry and blow air through a straw to dust my computer ?
Yes, that would be ok since the bread is used to make your mouth dry (and you don't have any other option). Just try not to accidentally let anything other than air out of the straw
