The Backyard Scientist YouTube Channel
This guy has a number of videos on do-it-yourself science projects he has literally done in his backyard! Some of these are not kid-friendly in the sense that they can be dangerous, so beware. The videos are awesome and show some very cool science experiments. For example, here's a link to a video in which he mixed molten aluminum in water beads. The result is super cool!
