If anyone is wondering: yes, you can own your very own atomic clock for a "reasonable" price! I encourage everyone to read [0] where a father takes his kids and a few atomic clocks up a mountain and back down. By looking at the clock drift due to changes in gravity, he was able to observe relativity! [0]: http://leapsecond.com/great2005/ |

Just to clarify, the clocks used to demonstrate gravitational time dilation were on the order of $10,000 (or more, e.g., [0]). But one can find rubidium standards online for a few hundred dollars.
