Why do you say do not do this? With my glass setups, during shed, I put very damp moss underneath the warm hide and never had an issue.
Edit: posted too quick. I would not recommend putting boiling hot water inside the enclosure.
Edit x2: I'm really having a hard time comprehending the boiling water thing. Lets say you do it, watch the snake, snake goes for the water, you intervene, and in the hysteria, you both get burnt. It's not like water is going to stay boiling for a long period of time to have any benefit. Just a dumb idea all the way around.
