Take a look at the brand new Journal of Visualized Experiments which wants to publish video films of experimental work to help apply laboratory protocols. The “YouTube for test tubes”, as news (at) nature writes.
The editors’ explicit aim is to help researchers reproduce biomedical experimental procedures, but it certainly has museological applications as well. These videos is a reminder how thoroughly materially grounded these practices are. We are very far from inscriptions á la Latour & Woolgar here. This is laboratory work in its original meaning of manual labour.
