Thanks! I'll play all videos tomorrow instead if Fireworks this year ...

I approve, but needs more fluorine.

Awesome post! Brings back many fond -- and some not-so-fond -- memories of HS and college chemistry classes.

One of my favorite posts in a long time.

A shortened version (1:09) of the Previously for Caesium which never fails to make me laugh at the end. I loved chemistry for just this sort of thing.

Heh, I'm a nerd. I've already watched almost all of these, except for the awesome compilation.

Poor, stoic (if bemused) Neil. "Yeah, I already know what's going to happen when you do that. You're either going to blow up my fume hood and/or make a huge mess for me to clean up. Fine, just let me go get another fire extinguisher and a broom."

I'm also quite concerned about Deborah Kays' lab coat. Partially because it looks like it could burst into flames if you get the wrong drop of something else on it, but mainly because I'm worried it's going to spontaneously create potentially harmful organometallic life forms.

At the end of the compilation you can see them blowing up a balloon of hydrogen. I've seen the original before, but I just now noticed that in the background up the hill behind a stand of trees there's a student walking who seems to be quite surprised at suddenly hearing an explosion. They seem to jump a little, then stop and look around. Awesome.

One of my best friends is a science teacher at the high-school level (this is in Ireland) and was lamenting once that she had to keep a whole store of these kind of whiz-bang experiments in her back pocket once to keep the kids' attention -- explosions, colored flames, stink bombs. "Basically," she said, "my life is bangs and smells."

....It's still cool. (I kind of want to get sulfuric acid and sugar and play with it just because of what it does.)

Yeah, it ends with one of my favorite tricks, lighting a balloon filled with hydrogen. This sort of stunt is probably why I was rushed to the Emergency Room twice during my high school chemistry classes. You should probably wear safety glasses just to watch these videos.

The Aqua Regia one was really interesting. Thanks for the post.

I don't mean to be "conspiracy guy", but uhh- who's operating that camera on the moon as the lunar module is flying away? I imagine an exchange like this "oh wow guys I got a great shot of you blasting off! Hey wait a minute. Hey guys? Guys?"

For that mission and a few others they had a remotely operated video camera on the Lunar Rover, which explains why the framing and panning/tracking isn't so great.

They intentionally parked the lunar rover a safe distance away specifically so they could get that shot because even the folks at NASA wanted to know what it looked like lifting off, because in the earlier landings they didn't have the rover or live color TV cameras. (Despite history's rosy-colored hindsight, people didn't actually "watch" the first landings, but they may have "heard" them, even if it was on TV.)

mike3k, sometimes a column of carbon is just a column of carbon.

Uh huh. Once again they didn't dare show the iodine tricks.

This is an excellent post. Thank you very much.

Also, episodic, I laughed at the end!
