One of the most complicated problems of Science is to reach full reproductibility of experiments. Even more, it is merely an issue of knowing how one experiment was done. It is in this context of research and education that the JoVE (Journal of Visualized Experiments) web site was created to present videos of some scientific experiments.
It is not always spectacular. Most of the videos will probably not bring a Nobel prize to their author, but there are plenty of interesting things, like this dissection of Drosophila ovaries (the Drosophila fly is the most common guinea pig of biology).
