Interesting Fact: To keep up with larger time capsules Davisson built a second time capsule, in 1983 directly over the first one so there would be no question as to whose time capsule was the largest in the world. In the second time capsule Davisson entombed another car, a beat-up 1975 Datsun or Toyota (no one can remember which) to show what society does to a car in ten years. Davisson died in 1999 at the age of 91.
