The totally boring-b**ls**t
physics/chemistry-demonstration kit for schools that was put out in the early '70's by Harcourt, Brace & World, Inc. The accompanying lesson-sheets were always irritatingly difficult to work with, and the company seemingly couldn't even spell "classroom" properly on the
box's cover --- for years I had always thought it said "glassroom" because the
bottom of the "C" and the top of the "L" were interlocked, and so it made
da "C" look like a "G".... it was only when my fourth-grade teacher actually mentioned the
name of the kit when speaking to another student that I finally realized what the label actually said!
Science
class is spota be fun, but don't count on any
happiness if your school relies on those insipid "Glassroom Laboratory" kits to teach
da subject --- arduous and yuckyyyy...!!!
