Will It Lens?

A couple weeks ago, Dustin got a whole bunch of people to each contribute a few dollars, and we bought a four foot by three foot fresnel lens. It arrived earlier this week, and we've been spending our lunch hours out in the sun playing with it.

You forgot the safety disclaimer about telling people *not* to put their hands into the light (like I do repeatedly). ;)

It's the fourth sentence of the "SAFETY NOTE" paragraph. I can't help it if you refuse to read the safety warning and ignore the rest of us when we plea with you to get your hand out of there (re: the cup of milk). I'll just keep photographing. :-)

However, I and a bunch of other people would feel better if you had some sort of tongs or something to keep your hand farther away.

Think of my hand in the light as a train wreck. Yes, everyone would prefer that I not get burned, but it makes the experience so much more exciting to watch ;) .

I also wouldn't do it if I believed that I would get burned; I'm not a masochist. I trust the lens carriers to keep it steady, and I trust my hand to be steady. Discussions about my sanity in trusting others with a lens that could burn my flesh instantly are still open.

I agree that in normal conditions, you won't burn your hand. However, I'm concerned about unusual events. If there's a medium-sized earthquake (like that 4.5 we had a couple months ago), your hand gets burned. If a bird craps on one of the people holding the lens and they get surprised, your hand gets burned. If something boils/pops/etc unexpectedly, your hand gets burned. That's the sort of thing I'd like to avoid.

I appreciate your caution and concern, but I continue to be unworried.
