my kids will probably never even know what this is - so sad. Put this in a 45 record to play it on a 33 setting. Doesn't make sense, does it? You really need to know how this works to understand the concept.
Remember having to lay our heads down on our desks and rest? When you think about it now, it was just so funny!--"rest period"--usually after lunch. Gosh I forgot about this! We do do it at least till fourth grade.
