<p>[QUOTE=&quot;Burton Strauss III, post: 2401381, member: 59677&quot;]No, it wouldn&#039;t work - the coins would be pushed to the outside by centrifugal force and held there. You would need to pulse the salad spinner, let it slow down to tumble the coins, and repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat, repeat ...</p><p><br /></p><p>You would need something like a rock tumbler at VERY VERY low speed (rock tumblers work because at low speed the centrifugal force isn&#039;t enough to hold the items against the wall at the top of the arc, causing a tumbling action <i>somewhat</i> like the pants pocket jingle). And as long as we&#039;re in hypothetical experiments, toss in a couple of socks so there is some fabric to rub against.</p><p><br /></p><p>(And no, I don&#039;t own a rock tumbler - since I was 9 or 10 - and no, I haven&#039;t tried it, it&#039;s just a thought experiment).</p><p><br /></p><p>But I&#039;m with Dave, I don&#039;t get it either...</p><p><br /></p><p>PS: <a href="http://www.livescience.com/52488-centrifugal-centripetal-forces.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.livescience.com/52488-centrifugal-centripetal-forces.html" rel="nofollow">http://www.livescience.com/52488-centrifugal-centripetal-forces.html</a>[/QUOTE]</p><p><br /></p>
