I don't actually know what it's called. It's definitely a chinense, but I got seeds from it at school and it's not identified. Incredibly sweet though, not hot at all until you get to the top of the pepper.
I didn't. It really, really hurts. The laughs I get from people nearby and the endorphin rush make up for it. Eating enough of them can make it hurt less but you will never be able to just eat them straight up without problems.
