It might not rupture, depending appon the material it&#039;s made of and the thickness... (for instance, I know some have made small-bore diaphrams out of plain rubber, and I know that tupperware lids often find themselves in use.) At least, it deserves a mention in the artical. Not much of a &#039;handbook&#039; if it only tells you how one of the most common valves works, but not how to build one.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
