Remember Ditto machines? If not, I'm sorry you didn't get to experience this wonderful contraption with its accompanying odor.
It was always a huge treat when the teacher passed out fresh "ditto paper" with that pretty purple lettering. Mass inhaling ensued as each student immediately put the paper to their nose. It was even depicted in the movie, Fast Times at Ridgemont High. Sadly, no other generation will be able to inhale that unique odor.
It was determined that the fumes from pure methyl alcohol might be a bad thing. Obviously, technology also had a hand in the demise of the Ditto machine.
Besides the smell of puppy breath, ditto machine ink is one of the best smells ever! If I could travel back in time, one of the things I would do is sit in Mrs. Grenfell's class as she's handing out ditto paper. Yes, I'm a simpleton and lame.
