This is a simple way to make spring-steel reed valves for valved pulsejet engines like those found on model aircraft. All you need is a suitable piece of spring-steel, some paint, salt, water, a 12V battery or charger and a couple of bulbs.
Who would have thought that electrochemical etching could be so easy or effective?
