At waxy.org, Andy links to the story of an Indianapolis mom arrested for letting her 5-year old son smoke crack--from her baby food jar bong.
In addition to being "horrendous," giving crack to babies is so nineties, it should be avoided. Making a bong out of a baby food jar, on the other hand, is apparently a timeless stoner tradition. Of course, I have no firsthand experience, but based solely on the diagram here, I'd wager you could also make a bong out of a Japanese snot siphon.
