Colbert_Frangible_Nut

Stephen Colbert received a frangible nut from the crew of STS-135. But it does not appear to be from the actual STS-135 mission - the frangible nut design was changed in 2008, to accommodate a pyrotechnic link between the two explosive charges which fracture the nut. www.nasa.gov/centers/marshall/pdf/290339main_8-388221J.pdf
