makin a bong, and i have to choose between having a bowl that is aluminum foil, or having a stem with a little rust inside.
If you have a dutch oven, you can make a pot roastBeef round top tends to be on the tough side, making a pot roast in a dutch oven would allow the moister to seep through and make the meat more tender to the palate.

Always use a crock pot, put meat in pot and add a package of Lipton Onion dry mix, meat will be so tender when done it will almost fall apart, I like to eat it with horseradish myself.
In typical use, during combustion, the smoking material in the bong won't get hot enough to melt or oxidize the aluminum foil (don't ask how I know this)As far as the stem with rust, you could tape some sandpaper around a thin dowel, or use a rat-tail file to clean out the rustProbably, if you are worrying about lung damage, you should worry more about the substance being smoked than the aluminum oxide or rust.
