Youtube Mashups for my first year chemists

I've found Youtube videos to be very helpful for my students who some of have never even handled a beaker.
 
Here are some examples for my titration part of the laboratory:

Do you have any idea how many of your students access these? Have you had any feedback on whether they find them helpful?
One of my colleagues, Tim Dargaville, is making some showing the calculations for some of our tutorial problems; we plan to try to track their views (they will not be in the public part of YouTube).
