I place a glass insert inside the Pen and Pencil holder to turning it into a Flower Vase.

I bought a used microwave from Goodwill and took out the transformer. 2,000 volts

These are mounted on a base to display on a table or shelf.

These have picture frame hangers on the back so they can be hung on the wall.    

After I electrical burning them I use a stainless steal brush under running water to scrub off the ashes.

I coat the surface of the wood with a mixture of one table spoon of Baking Soda to a cup of water. This makes the wood conductive to electricity and the voltage follows the path of least resistance.

Several coats of clear Polyurethane.

To do the pen and pencil holders I attach them onto a screw. I attach one electrical lead to it and the other to a probe.
