I've been absent for some time, but now I remember why I used to come back. Thank you for this great insight on flower pictures and not belated free daily horoscope, I will try and check back more often. How frequently you update your web site? Try checking out Port Perry houses.

I have not checked in here for a while as I thought it was getting boring, but the last several posts are good quality, especially this one about nice reads, so I guess I will add you back to my everyday bloglist. You deserve it my friend. Just be careful in reading you might get sleep deprivation it can cause you being impaired from your daily routine. Check out also spine anatomy.

The "my chemical mishaps" page is proof that there are two types of chemists: lucky ones, and dead ones. *shudder*

HSC Chemistry. 1988 or therabouts.

We were doing some experiment with Potassium Bromide and a very weak nitric acid solution.

Friend approaches our bench asks "What do we add the KBr?" we say that (pointing at jar of concentrated nitric acid) and then blah blah blah.

Seconds later... teacher asks "who has the concentrated nitric acid?"

Seconds later... a wierd "FWOOOOOOSSSHHHHH!" noise from back of room.

Scene: started friends in shock as test tube violently spouts pure liquid bromine straight up. It vapourises instantly forming a cloud, which drifts across the room, precipitating and raining liquid bromine on anyone silly enough to get underneath it.

Hilarity. Mayhem.

I didn't do well at Chemistry, but I had fun!

Nice voice. I pictured Jaws:

I've always taken great pleasure in cheerfully pointing out how many things in this word will happily kill you if given the right opportunity. Bern: Reminds me quite a bit of Derek Lowe's Things I won't work with blog.

If you want unwise experiments, I made chlorine gas, enough to see the color, in a high school science class - just electrolyze salt water. (Do keep the two gases separate, though.) [Boring people who don't like bits of glass bouncing all over the lab put the test tube for that reaction inside a metal tube with a window for the light to get in. -Dan] Unfortunately, there's no really good way to trap the chlorine, since it dissolves well in water. We just let it bubble into the classroom. (No, our experiment was not the most unwise one running on that public demonstration evening. I still remember our teacher came running for the fire extinguiser with a look of glee on his face.) But if we had been really unwise, a U-tube and some dry ice in acetone would have allowed us to collect liquid chlorine. (Note the absence of gloves and corresponding presence of bandages in that last link.)

Haha! You're right, that "My Chemical Mishaps" page is hilarious...

It's somewhat wondrous that he survived long enough to write that page up!

I especially liked this bit about the pipes he used for the phosphorus experiment:

...when I took them apart they bust into flames. When I cleaned them they burst into flames, when I looked at them weird they bust into flames, heck, let's face it, they were busting into flames just to be bursting into flames.
