How old is 'older brother'? Explain that most snakes* (giants, not so much*)- are very picky eaters and we aren't on their menu. Unless we've been handling their food first & didn't wash up ("life is better when you don't do that"), the main reason snakes bite is fear & self-defense...so have some sympathy for that scared little reptile! The only thing in nature that normally picks up a snake is a predator about to eat them: with gentle treatment, most snakes learn we are safe to be around and they relax.

Teach your brother to pay attention to the snake's body language...and to remember that snakes do NOT identify food by vision alone...movement they see gets them excited, hoping for a snack, but don't take it 'personal' when a snake chases your motion thru the glass, because once you give* them your scent, very few still try to bite. *blow across your hand, so your scent goes in the cage thru screen/vent & watch the reaction, most back off quickly. Knowledge conquers fear.

Then remind him how important snakes are in the web of life..."nature's best mouse-traps" and environmentally-friendly too! Either WE have to learn to catch & eat rodents (which multiply at warp-speed) or be happy that snakes do it for us, LOL!
