    Did you ever see the fake cesium in a bathtub video? They blew up a ceramic bathtub full of water with about a gram of cesium. I don’t buy it.

    Do you guys ever run into moisture concerns in your cesium fountain? I assume it is in high vacuum right?

  2. I have seen the fake bathtub video.

    We keep our cesium and rubidium under vacuum when in the clocks, and it comes in a sealed ampoule with argon. We break the ampoule in the vacuum system.
