off topic, but need assistance.

 

Hey, all you imaginative flow-types:

We've got a small liquid nitrogen dewar for storing frozen cells - the
kind that holds six canisters, each for four canes.  And we've got
something - probably a cane of piece of cane - that's gone AWOL and is
rattling around the dewar and preventing the canisters from fitting
properly.  I emptied the entire thing out and could hear something tinny
rattling, but because the dewar has a very deep, narrow neck I couldn't
see it or reach it or shake it out.  Does anyone have any scathingly
brilliant ideas for dealing with this?

Thanks much,

Fran
