<p>[QUOTE=&quot;desertgem, post: 3223475, member: 15199&quot;]Sputnik startled the US Science Educators and the Military,, who in 1957 found themselves listening to beeps from space that the ( considered less science sophisticated) Russians put up, reacted strongly to catch up and surpass the Russians before they could put weapons in space. Money and resources came to almost every high school in the US, for sciences that could be applied to space science. Chemistry was one such science course, which in my high school originally had seemed like cooking class, became more intense. By the early 60s, this experiment was published in most high school and even middle schools&nbsp; labs as it showed visually how chemical reactions could occur. Reactants were mostly safe , and the student could take the silver colored and gold colored cents home to amaze their families. Very popular, and the reactions worked best with new clean cents, which the banks then got in 5000 coin bags and were happy to supply for science. During my college classes , the beginning chem lab manual had this also. When I started teaching as a college Chemistry teacher, we made hundreds of cents ( all 1960 era) which were taken home and eventually ended up in the change bucket or spent. Now the 100% copper shell cent works better than the older bronze.&nbsp; Jim[/QUOTE]</p><p><br /></p>
