Michelle's Candied Corns!
do you have any ky jelly or petroleum? if you're going to let him try on his own maybe keep applying some along the top & sides of his body to make it slick--I think putting it on his ventral scales (underneath) might make it hard for him to get a grip though
Definitely a good idea.
I would leave him be for a few hours- if he doesn't get out by morning it think breaking the glass may be your only option. Be sure you cover him as much as possible with a towel before doing that though.
