Amazon's Jeff Bezos building giant clock in Texas cave
Amazon founder Jeff Bezos, who has recently been recognised as the richest man on earth, decided to utilise a part of his profits on building a giant clock. He posted a video of the clock being built in a remote cave, in Texas. The clock is unique in the sense that it is meant to last some 10,000 years from now. It is a reminder for everything that is happening or will happen from now on. The all-mechanical clock will stand 500 ft. tall when completed.
