What you need to achieve the steel wool technique is simple to find: a stack, a steel wool, a kitchen whisk, a chain .. and obviously a camera! You have to attach the chain to the kitchen whisk, put a steel wool inside the whisk ... you just have to rub the pile against the straw, this will cause a short circuit that will cause many small sparks. As soon as the first sparks appear, the whip mustbe rotated and the photograph can be taken with a remote control.
