<p>[QUOTE=&quot;-jeffB, post: 4934256, member: 27832&quot;]If I can ever figure out how to protect the camera, I should do a video of my big Fresnel lens focusing sunlight on a Zincoln. It (like the laser in this video) doesn&#039;t just <i>melt</i> the zinc, it <i>boils</i> it. I actually got a &quot;pop&quot; out of one cent.</p><p><br /></p><p>I do wonder what will come of all these high-powered lasers becoming so easy to get. When I was a little scientist, lasers were <i>expensive</i>, and that made it easier to enforce the rules around them. I remember needing goggles and training to even <i>enter a room</i> where a 100mW laser was operating. Now any fool with a few hundred bucks can buy a handheld five-watt (<b>5000mW</b>) laser and wave it around like a flashlight. I&#039;d say &quot;it will end in tears&quot;, except the tears will be puffed into steam too. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
