Yeah, somebody should start acrylic Q&A thread but won't bother cristopher neither!
When I tried to bend it it looked like hell, nowhere to get that pretty dichloromethane solvent, and I didn't even know there are such things in existence as acrylic tubes! :p

Green laser light being diffracted through something weird... Can't make out what that "hook" on the left is. Maybe a long exposure of drifting fringes from a interferometer?

This was not too cool when it happened, but in 1985 I was on an Iberia airlines flight from Frankfort to Madrid and it taxied into a fuel truck after landing. It felt like someone chucked a log under the left main wheel. The stewardesses weren't too happy with me snapping shots of the fiasco. Most of the other passengers were Germans and at that time I spoke enough German to be amused at their sarcastic remarks. We had to de-plane out the rear airstair. (It was a Boeing 727 btw)

Kind of old, but these are some nice close up shots of my xenon short arc lamps. It would be interesting to get a shot of one running like through a darkened filter of some kind, but I'm not sure just how to go about it.

Jeez, those look like they mean business! Did you ever get one to light? I remember trying to get a smaller mercury short arc lamp to light, it was a total pain since it took something like 2kV to strike and then 12V @ 10A to run. That was before I knew about Tesla coils, though, it would be easier now When I finally did get it to strike, I was shocked by how bright it was (and probably dangerously UV-rich too...)
PS: Do you know what the cooling requirements are? Those lamps look like the kind of things that would explode violently if they didn't get enough airflow.
To get a picture of the arc, I'd use a pinhole camera to project it onto a piece of white paper and photograph that. The arc in mine looked like a tiny sphere about half the size of a rice grain.
