["Safe" 5000 V]

ooops, sorry I've mistaken then units. I correct my last post: for 0.5 m spark you need 1.5MV = 1500 kV = 1500000 V, so with 5000 V you can get a spark of almost 2 mm.

["Safe" 5000 V]

Let's do some calculation: to make a spark between the two gloves, let's say they are 0.5 meters apart from each other, since dry air discharge break voltage is 3MV per meter, you need a 1.5MV = 1500 V (DC voltage) between your hands. I wouldn't play so close to it. Besides 5000 V seems to me extremely exagerated to obtain the spark.
