and fail
They built a nuclear bunker in Tulsa, OK to withstand possible attacks from Russia. They made part of it a time capsule - they put a car, various trinkets and leather goods, etc.
But they didn't make it waterproof. The car rusted out, the leather rotted, everything is destroyed - even the microfilm which records who was supposed to win the car, in 2007!
