I stumbled across this randomly on YouTube today and had to share. The first 3/4 of the video are a chemistry experiment breakdown of what goes into a glow stick and what each of those ingredients is meant to do. But what makes me LOVE it is that, at the end, all of this coalesces into a fine explanation of the difference between light-absorbing dyes and fluorescent dyes. Come for the glow-stick "how to", stay for the better understanding of how light works and how it influences what you see!
I'm going to bookmark The Debunking Handbook, a quick-read pdf with all sorts of great advice for effectively countering misinformation. It's put together by the same people behind Skeptical Science, my go-to source for detailed, easy-to-understand debunkings of pretty much every climate-science-related myth you can rattle off.

This custom silver ink, developed by materials researchers at the University of Illinois, Urbana-Champaign, allows you to draw working circuits out on paper. It's extremely cool, and the video shows you step-by-step how they make it. Bonus: This ink provides an actual reason to use cursive.
My friend John Mills has been integral in running the Duck Pond – one of the larger and more well-organized Burning Man theme camps – since 2005. Those who have been to Burning Man probably know this camp as the one with the giant slip 'n' slide and the radio tower with a yellow duck on top.
This year John is unable to attend, so he's focused his energy into helping the community by writing an extremely detailed account of how their camp works and how to run your own. I helped John edit this post, and as a total Burning Man outsider I was amazed at how much work and thought goes into throwing a week-long party in the desert. Even if you're not interested in Burning Man, I think you'll find this insider's perspective on the culture and innovation behind the event extremely interesting.
