When my daughter did a poster charting storage capacity of computer media, I got out a variety of things so that she could draw at scale the media (from memory, 5.25" floppy, 3.5" floppy, Zip disk, Compact Flash, and SD Card). I gave her a 5.25" floppy to take in and show as part of her presentation -- her _teacher_ asked if she could keep it since she had never seen one.
