Apollo 7 had received the medal twice before, for his Mercury and Gemini missions). Therefore, NASA administrator Michael D. Griffin decided to belatedly award the medals to the crew in October 2008, "[f]or exemplary performance in meeting all the Apollo 7 mission objectives and more on the first manned Apollo mission, paving the way for the first flight to the Moon on Apollo 8 and the first manned lunar landing on Apollo 11." Only Cunningham was still alive at the time; Eisele's widow accepted his medal, and Apollo 8 crew member Bill Anders accepted Schirra's. Other Apollo astronauts, including Neil Armstrong, Buzz
Silly Putty glycerine, and 1% titanium dioxide. Silly Putty's unusual flow characteristics are due to the ingredient polydimethylsiloxane (PDMS), a viscoelastic substance. Viscoelasticity is a type of non-Newtonian flow, characterizing material that acts as a viscous liquid over a long time period but as an elastic solid over a short time period. Because its apparent viscosity increases directly with respect to the amount of force applied, Silly Putty can be characterized as a dilatant fluid. Silly Putty is also a fairly good adhesive. When newspaper ink was petroleum based, Silly Putty could be used to transfer newspaper images to other surfaces, providing
