Does the rod exert a force on the foil?

Yes
Force=k(Charge of rod)(charge of foil)/distance^2
in this case, the foil's charge isn't 0 so the force isn't 0 either.

Yes. The negatively charged rod will cause electrons to migrate away from the surface of the foil leaving the positive lattice (atoms) in place. There will be attraction between the excess electrons in the rod and the local positive charge in the foil.

To be honest, you *could* have eaten the whole foil lid to the cream cheese and it would not really be an issue. Aluminum isn't really needed by the body, and is highly resistant to being digested. Given that the type of aluminum you ate is also very pliable, GI lacerations are not an issue. There is a very good chance that by the time you read this, you will have already passed it.
