I tried to describe to my kid the sound of a 5.25" floppy disc the other day. MMWA MWA mmmmmm MWAMWA mmmmmmm.

He has seen 3.5" discs, but never the large floppies. His mind almost exploded when I talked about games needing 7 or 8 discs and hitting certain points where the game would pause while you put a new disc in.
