A recent visit to the Texas Prison Museum connected with me on this project. I suppose it was seeing "Old Sparky", the retired death penalty electric chair, reading about prisoners, wardens, and guards of the past and their demise, and even reading lists of last meals and last words.
Old Sparky...a visit to the chair was referred to as "Riding the Electric Thunderbolt."
Some prison art...soap carvings, matchstick sculptures, etc.
A homemade blender!...and other inventions...
