"Why is it unsafe to look at the sun with this unrecommended method? The sun's dim enough, right?"

WRONG. The sun emits energy over the entire electromagnetic spectrum, from radio waves to gamma rays. You might be comfortable looking at the sun through that insufficient filter, but your eyes are being bombarded with ultraviolet and infrared rays you don't see, and may not be filtering. These both will do irreparable damage. It may not be apparent immediately, but the damage is there.

I'm not trying to be a wet blanket here; I love a good eclipse as much as anybody. But every year someone sustains permanent eye damage as a result of poor planning/unsafe viewing. PLEASE protect your eyesight!

AND of course enjoy the eclipse!
