Yup just like everyones said "Bag them" snakes dont like so much activity going around in front of there eyes. So when you bag the corn itll feel secure not seeing people walk buy. Not seeing your body move forward and back towards the tub scaring him. I dont want to be the one to tell you this but you should have the sanke in the classroom for awhile. I bet the snake is gonna be freaked out by so many visiters tapping on the tank, and from so much movement.
