Alternate: Cutting copper sheet & cardboard
step 3 of 6

Copper sheets instead of copper clad

Cut two squares from copper sheet

The idea is the same with copper sheets, using scissors cut two small squares of copper. It is probably best to use older scissors to not dull your good pair.



Cut a square of cardboard

Next we will prepare the insoluator from cardboard. Cut an identical square from a small piece of cardboard the thickness of a postcard or cereal box top is preferred. 

This cardboard will be sandwiched between the two copper squares below.


Make a copper-cardboard-copper sandwich

Using double sided tape, put the copper squares on either side of the cardboard. Trim the final square to make edges even.
