Taking a snake to class

[200xth]

On the 30th if this month I'm giving an informative speech on any topic I want for my speech class. For my attention getter I am going to use one of my ball pythons as a visual aid. However, the room is cold, like 60*-75* (that's Floridian freezing lol). I will only be speaking for 5-7 minutes and I think that I can have a friend r family member hold onto the snake outside until I go to speak. How would you guys pull this off?
I have several 72 hour heat packs and plenty of deli cup containers that I can put the snake in for transportation. Should I use a tub in a large brown paper bag with the heat pack? Or one of those pillow case bags. It had been about 80* outside lately so would the snake be fine in the building with just the heat pack?
Would it be better to just get a rubber snake lol. If it would be too stressful/risky for the snake then I'll just use a toy snake.

Thank you

You're not gonna need anything. He'll be fine for the short amount of time he's inside the classroom.
