Bromine is a wonderfully thick, soupy gas/liquid. Technically it's a liquid at room temperature, but if you have it in the open it will evaporate away at a high rate of speed, evolving clouds of reddish purplish vapor. Confined in a glass ampule, it's a thick dark gas, which is quite odd to look at.
Like chlorine, bromine is a highly reactive halogen, choking and toxic to breath, but entirely harmless when in the form of a salt or dissolved ion. People like to soak in sodium bromide solutions (see first sample).

Gas in a bulb.
The deep color of this sample is caused by bromine gas, not liquid. There is some liquid condensed on the sides of the bulb, but the majority of the color you see is the gas. I think it's amazing that a gas can be so thick. There's a very similar bulb under chlorine, but its color is much, much lighter. Normally when you see a "gas" that is colored, it's not really a gas but rather tiny droplets of liquid (in fog) or particles (in smoke) that make it look colored or thick. The difference is that in a real colored gas, there is no diffusion of the light, just attenuation. A fog or smoke makes things look fuzzy, while with a true colored gas, they look perfectly sharp, just colored.
I received this sample when Tryggvi and Timothy came to my sodium party.

Sample from the Everest Element Set.
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (excepted gasses) weight about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.
To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.
