Have people heard of this? I hadn't, until I saw the article in the WSJ the other week. Apparently the cool thing to do (at least in some middle school somewhere) is to take a wrapped roll of Smarties, to crush them a little bit, and then to breath in from the end of the tube and exhale it like smoke. There are a bunch of videos on YouTube, though not tons. This one is basically amazing. Seems the trend has been around since at least Dec 2007.
