Via Maitri, let’s hear it for Felicia, the Fermilab Ferret!
In 1971, this ferret played a key role in the construction of particle accelerators at Fermilab’s Meson Laboratory. As sections of vacuum chamber were connected together, Felicia would run through them, dragging a string. After she had carried the string all the way through, researchers would use the line to run a rag doused in cleaning solution through the long, narrow tubes.
I gotta say, reading that? Bucky’s not coming close to earning his keep.
