Yesterday, I wrote about this paper on chimpanzees learning (or not) to spit water into a tube to retrieve a peanut.
I was so very sad to see that there were no supplementary materials included with the paper. No awesome videos of chimps spitting water into a tube to share with you.

So I sent an email to Dr. Claudio Tennie, the lead author of the paper, and postdoc at the Max Planck Institute for Evolutionary Anthropology in Leipzig, inquiring as to the possible existence of a video. It seems that there aren't any available. But, he gave me a link to an awesome video already on youtube of an orangutan doing the exact same task!
