I had a constriction incident with a Burmese Python... twice. The first time was during feeding. He got hold of my hand and constricted around my arm. I poured a bottle of rum on his head and all that happened was I lost a bottle of rum and got a drunk snake. I had to have it pryed off. I've since learned that hot water over a snake's face will make them let go instantly. I've tested this a few times, twice with a baby Burmese and once with a huge one. Like... stick the snake's head under a tub faucet.
