Well, yeah, that's 'cause they're really small...
	In all seriousness, I haven't seen much distinction made in these posts
between Elmer's glue fresh from the bottle versus a diluted version. 
	Could it be that in "stock" Elmer's, the concentration of the various
solutes is too high for bacterial growth, in the same way that bacteria
won't grow in a concentrated sugar solution?  A diluted version of glue
made for dipping slides, on the other hand, might be quite yummy and
osmotically hospitable for bacteria. Someone like Jim who makes it up
fresh every day would never see any, though. 
	Something to think about and explore, perhaps.
