Dunk your hand and the snake in a sink full of water. Temps don't matter unless it's so hot it burns you or the snake.

Take some whiskey and pour over his mouth/head.

If you have a snake that has clamped on and won't let go, you need to stop taking a shower in Odour de Rodent perfume/cologne.

I've never heard of a ball latching on and not letting go. Usually they just give you a quick "get out of my face" strike. I've seen a ball clamp on when the person was feeding the snake without the use of tongs and his hand got too close to the rat and snake's mouth at the same time. The ball let go after a few seconds.
