Thing 13 - YouTube

I watch YouTube all the time, but usually for the music videos. The kinds we used to see on MTV when the M stood for music, not moronic. I usually try to avoid the amateur videos. But I have to say that there are some great amateur videos put on YouTube for educational purposes. I really liked the chemistry demos for a variety of reasons.
1. I can get ideas for class.
2. I can see how these demos are done. If there is only written instructions for a demo I can't always picture what is going on.
3. I can show these things to the class if I don't have the equipment, supplies or if it is too dangerous to do in class, such as dropping a chunk of cesium in a bucket of water.

One video I like and which is applicable is the following on creating Hydrogen gas and coincidentally it is called "Chemistry Experiment 13 - Hydrogen Balloon" which is quite appropriate since this is "Thing 13".
