  Sealed glass ampule, 99.98%.
Another beautiful cesium ampule from David Franco: He plans to offer these for sale on eBay along with a very similar rubidium ampule. The fact that cesium melts in your hand makes it one of the most fascinating element samples you can have: I never cease to wonder at the beauty of it. And the color is also quite remarkable: There are very few metals that are anything other than gray or silvery in color, so the delicate gold color of cesium is a real treat. (It's also very difficult to photograph: This picture does not do it justice.)
Just be very, very careful not to break the ampule! It will react explosively with any moisture (e.g. your hand, the air, etc).
I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
