Lucky you! I haven't had the chance to see any of my snakes shed except one time I caught my boa shedding but I could barely see anything as she was under sphagnum moss.
Recently I had to help my bp with his shed, he had only managed to get the skin off his head and 1" of his neck. Gave him a good soak in the tub and after he shed right in my hands, was sooo cool. I would just hold him a little firmly and he slid right out of his skin in my hands. The rest of the skin pretty much came off in one piece. Was an amazing feeling in my hands!!!
