Seriously, when I worked in prisons, people incarcerated can make most anything access most anything, including contraband. People who think prison is just bad food and workout in chain link cells and real bad punishment, are dreaming.
One of the most sought after is how to make contraband food like back to home. Recently I saw this innovation. But not sure it can replace the genius level women at Dublin prison who, when I was there, were experts at making melted cheese sandwhiches on the iron used for ironing clothes.
Sometimes the Mothers are the invention of ingenuity.
Thus, the sideways toaster trick.
