Here's one I took on a recent canal trip - a wagtail nesting inside a steel lock gate. It was actually quite hard to get this photo, but it came out quite well, at least after I'd done some light cleaning up in photoshop.

Cupric chloride dehydrating in a round bottom flask. The blue-green color is of the dihydrate while the anhydrous form is brown.

"Shoppin" hauls, from the yearly spring clean up in Delta. During one week, everyone can throw out stuff they don't want. A group of geeks get together with a couple of vans and a trailer and pick up useful (to us atleast

) stuff.

We got 19 microwaves in 2006, for tesla and other projects, along with lots of computer monitors and other stuff.

This year I had a vacuum cleaner fetish

, 18 of them I think. The recycling depot got a LOT of plastic after taking those apart.

. We also got more microwaves, some very nice CRT monitors, and a 2.4GHz computer that just needed a hard drive.

Man, Dr. Spark, you are lucky to live so close to the Rockies. I would love to be able to hike up there more often, but alas, I've only ever gotten the chance once.

Speaking of glasswork, anyone seen or made 'Prince Rupert Drops' in person?

I made some last week. Verry interesting project.

[meant to post this earlier]
I made some of the drops on fourth of july weekend, but on some of them I accidentally burned-off the tails... I could not break them with blunt objects to save my life... I have not tried cutting tools though, and I still have them around here if you can suggest a way to break them...

Kids, stay away from table saws.... Even when your hand is well away from the blade you aren't safe!

I was making the last cut on a set of pieces to make a plexi box, and a little piece of plaxi got stuck in the blade (I didn't take a pic, there was just a little strip curled up in one of the teeth) which caused the piece to jump and drag across the blade. That wouldn't have been too big of a problem, except for the fact that when it grabbed it slipped out from under my hand, and dragged my hand across the blade...

The piece of plastic I was cutting, you can see I was almost done with the cut (and it was the last cut out of about 12) then the blade grabbed, and dragged the piece across the blade (quite quickly as you can see, the blade I was using was about 100teeth, turning at at probably 100rev/sec, so if it moved 1/4" between teeth the piece was moving about 100-200mph) My thumb was at the notch (there was some flesh there after the incident) slightly above the line of dings.

Me after the doctor stitched my finger back together:

And my thumb after they were done with it. Sorry the picture didn't come out well, we only had a cell phone and the er wasn't all that happy about us taking pictures to start with. I am only going to link it since it kinda NSFW

The cut along the left wasn't that bad, so they stitched it up, but over on the right the flesh was just (and I quote) hamburger meat so they did their best to sew it together and I go back in 45 hours to see how it is healing.

Lessons learned:
1. always keep the blade as low as possible... The only reason I have the tip of my thumb a all is that only 1/4" of blade was sticking up so it could only cut so deep
2. Keep your buddy around. I had my brother home but he decided to go to sleep and even banging on his door didn't wake him... Ended up calling 911 on my own and he finally came rolling out of bed when he heard the paramedics...
3. Never let your guard down... My hand was a good 6" from the blade, there was only a tiny sliver of blade showing, but still I am lucky I can use my thumb at all...
4. always apply pressure to a wound. Luckily they shoved that down our throats in the boy scouts, but in the 15 seconds that I was freaking out trying to figure out what to do I lost probably 10cc of blood, after I wrapped it in my shirt and applied pressure (even if it hurts its better than passing out from blood loss) it stopped bleeding almost immediately.
