In the late 90's I was an instructor in a youth PC repair class. For a fun demonstration we took an old IDE drive, removed the lid and had it running defrag. We did this outside. Next to show how important it was to prevent liquid spills we poured some cola directly into the drive. It sprayed everywhere but the drive kept working fine. Kids got a good laugh and did not learn a lesson that day.
