> colon is THINNER than this
While, in general - I agree with your sentiment and like the idea of showing teens a sausage casing….
realize, the colon is not "thinner" since the colon from an animal IS the sausage casing…
just saying I hate to use science to give even tiny incorrect facts…they won't believe you later if you don't have it wired - it is the same.
good idea though.
