<p>[QUOTE=&quot;desertgem, post: 3604462, member: 15199&quot;]This experiment can either be done as my previous post&#039;s url given or as electroplating with a small 9v battery. It is a favorite of home schoolers are well and has been included in quite a few lab books/teacher guides for 7-8th grade levels, 9-12 , and to beginning chemistry in colleges, and the supplies are packaged by several science supplies companies for school orders. I would have no idea how common they really are, but the forum keeps seeing more and more pop up, so I expect many.</p><p>The experiment itself became popular in the late 50s -early 60s during the Space race after sputnik.&nbsp; Jim[/QUOTE]</p><p><br /></p>
