Prison mesh, also known as prison fencing, is a type of security fencing used primarily in corrections facilities to prevent inmates from escaping and unauthorized individuals from entering. Made from high-strength steel wires woven into a mesh pattern, this type of fencing is extremely durable and difficult to cut or climb.

This unconventional technique, dubbed alternative soldering, utilizes readily available household items in ingenious ways to achieve reliable soldering connections. One such method involves the use of a candle flame and metal objects like screws or nails as substitutes for soldering irons. By heating the metal object in the flame until it reaches the necessary temperature, enthusiasts can melt solder onto the joint, creating a bond similar to traditional soldering.
