I uploaded this Video that someone sent me in a email. So I didn’t teach or film this squirrel. This takes place in England - the owners of the yard added each piece of the Rube Goldberg contraption slowly so that when the squirrel learned one section and got the nuts, they then added the next section. Finally it ended with what you see on the clip! It took over 2 weeks to get to this point.
