Building on Jeff's interesting input: 50 lb animal licks are to be had
in any country district They come in 3 general varieties:
A salt block (white)
A mineralized salt block (brown)
A protein loaded mineral block (brown)
These are listed in ascending price starting around $6 or $7 in these parts.

We did this experiment as an undergraduate modern physics laboratory
exercise using a salt block in the early 80s at Oregon State. It is
my understanding that the apparatus was originally created as part of
a master's thesis project (from the appearance of the apparatus--many
years earlier). My recollection is that the block was in the shape
of a cube of edge length about 1 foot, cut along a plane containing
two opposite edges of the cube, thus creating two 45 degree prisms
(that is the cross section of each was a a right isosceles triangle).
Given that OSU has a huge agricultural program, I am assuming the
cube was a livestock salt block. Looks like slightly smaller blocks
are inexpensive and easy to obtain. See

and perhaps a 50 lb brine block would do the trick (search on salt
block at amazon.com).
