Yes, good idea on the mineral oil - that would definitely work!

To see more specifically what else I am after, please take a look at this

I am interested in replicating this general concept, but building
stand-alone exhibit components that don't require facilitation.  I'm
looking for any tips on how to build the "syringes."

Thanks for the input so far.
