By superheating it, I believe Jeff means a dead frozen rat and heating it to be very warm. I always try prekilled before live so as not to hook the snake on live, but that doesn't always work.
Did the snake eat before? Rats, mice, live or dead? Maybe he simply wasn't hungry? Happens. Try again in a week?
To scent a prey item, you basically rub the mouse on it. On my big female, I scented rats with mice and made sure if I could to rub some of it's blood on the rat (I know, icky-- but it worked.)
Patience is number one in feeding balls. Make sure his temps, humidity, etc are all right. Make sure he has good places to hide. Don't go freaking him out by trying to feed him every other day. Maybe offer prey once a week to ten days. It will eat when it's hungry and feels absolutely safe. They can go for a long time without eating. As long as it is healthy and not losing lots of weight, no worries.
