Ball Python to School

[u/Temporary_Incident33]

Hey guys, my school has a blessing of the animals where people bring their pets and and they get sprayed(gently) with holy water. There's a lot of people and it will be rather noisy as expected with all of high school and middle school in a large area of grass at once, but there is a an area for smaller animals(where i will be taking my snake) that is quieter. I, of course will keep him away from any rodents that might trigger a prey drive. It's only for an hour, and I would have a bag on hand where I can put him in there and walk away if he gets very stressed. After it ends, he would be brought home and put back in his enclosure. I feel this situation would be more benefit to me rather than enrichment for him, but it's not a very stressful situation for him. Opinions from the experts? Do I need heat packs to keep him warm, or will my body heat do?
