Fluorine
I had always heard that fluorine was a brownish-yellow gas, but I always wondered how anyone knew. You cannot keep fluorine in a glass container since the glass would burn. If you keep it in a copper cask, you can't see it. And if you tried to see it outside a container, you would die from inhalation. But today I was browsing the internet and found the first picture of fluorine gas I have ever seen, shown left. For the story of how this sample was prepared, see here

Shameless promotion

Tak yo, brotha
One thing you can say about Czechs is that they sure like saying "Yo." But they can't quite say it with the same macho musicality as our brothers from the 'hood. In fact, they sound downright whiteboy when they say it. I suggest they could benefit from some tutoring lessons or exchange program with the Eastside.
Update: Sveti correctly reminds me that Czechs say "jo", not "yo."

Flesh wound
Recently I was putting together some furniture and I made a mistake, installing the wrong type of screw fasteners. Since they were now bored into the wood, they were very difficult to remove and the only thing that seemed to work was prying with a knife. The knife slipped and I stabbed my left hand. It hurt.
