Did you know that the 580 is strong enough to burn? I am an idiot I was playing with the flash that I just got... had it on full power "popping" it admiring its insane intensity.. guess what I pointed on my couch... was just fiddling around and fired it off... now I have a black burn mark on the couch.. OOOPooooppsss

Look the bright side, at least the couch didn't catch fire. Any pictures?

Well the flash was actually sitting on the couch (yes flash pointing down).. I had been playing around admiring its strong flash had been just goofing off took it out.. made a couple neighbors wonder why it was lightning while it was snowing . Butthen I was watching the basketball game just learning the different things about it when I accidently fired it off while I was just playing with it in my hand. weird thing is, if you fire it while up close on your hand you don't feel any heat. oops... idiot.

you should also note photons have the engergy to move objects. obseve a index card laying over the flash lens will be knocked off the lens by the light of the strobe.

i first observed this with a sunpak 555 potato masher, now that thing probubly a little more power than the 580. but i think it should work.

Actually, it is the heated air that moves the card, and not kinetic energy imparted by photons. It was a good observation though.
