Given the background description of some cooking related query, summarize the question into a title

[EX Q]: What are the mechanics of water boiling over? How can you stop it from happening? Is it more likely to happen with certain ingredients? Which? How does the amount of water effect the likelihood of water boiling over? What role does burner temperature have? Will it only occur during a rolling boil?This is brought up by this comment by MeltedPez in one of the cooking pasta questions: The only other argument for using more water is that less water is more likely to cause the pot to boil over. Basically the starch in the pasta makes it easier for the water to form bubbles that collect and spill over when not paying attention. I've found that with a very low pasta to water ratio can end in a messy kitchen. This seems very counter intuitive to me initially, as I feel less water should make it harder to boil over the edges.

[EX Q]: I am going camping shortly. I have done some dutch oven cooking before, and there is one recipe that I want to make that uses one. However, I do not have a dutch oven...I am thinking of using two aluminum pans (the cheap foil ones) and aluminum on the top (several layers) to make a sort of dutch oven alternative.Has anyone tried that? Does it work?I am also thinking of putting some sand or water between the two pans to make it hold and transfer the heat a little more evenly. Anyone know if this will work?
