Step 4: Make The Insulating Spacers The Three conductive sheets
are held apart by insulating spacers. Pushing between the
spacers creates a conductive path. The insulating spacers are
the white dots that are made by screeding Oogoo in the holes in
the stencils. The stencils are made by drilling 1/4" holes in
1/16" plastic sheet. The holes are drilled 1" apart with the
holes in the second stencil drilled in between the holes in the
first. Screed the Spacers Step 4 pic shows a small mix of Oogoo
(2 silicone caulk to 1 corn starch by volume) being screeded on
one layer of Oogoo II.
