From what I understand, it can be done. However, foil is not very efficient. I have also read that there may be NaOH left from the extraction which may react with the foil. Really though, a glass bowl is ideal so that one can take large hits without wasting much and get a proper, quick dose. I'm not sure about the NaOH reacting with the Al, perhaps someone more versed in chemistry can clarify.
