Well, not to be that guy (actually definitely to be that guy) but what Newton discovered was that gravity was proportionnal to the mass of the bodies, and to the inverse of the square of the distance between their center of mass, and this second point seems too difficult to prove for a 9 years old.

I need to survive for 3 days without pooping, and eating as little as possible. I can pee, but not very often. It can’t take up too much space. What food do I pack?

Please don’t ask why I need this.

It would be great if the food also made me sweat less.

It has to be something I can easily find.

EDITS FOR CLARIFICATION:

I am not planning on partaking in any illegal activities.

I do not condone the use of illegal substances and am not planning on smuggling anything anywhere.

I am not going on a hiking trip or mailing myself anywhere.

I will be staying in a tent (not a small one; a huge with with air conditioning and everything). I will be traveling for five days, returning to my current location on day 3 and traveling again on the last two days. I will not poop on the first three days (hopefully).

Clean toilets with all the expected facilities will be available to me. I am not going to poop for reasons that I wish to keep to myself.

If it gets bad, like really bad, like a-piece-of-poop-is-literally-halfway-out-my-ass bad, I will use the toilets.

Please stop asking because I am not telling anyone the reason.

Could someone please explain me the context? I haven’t followed the strike very closely.
