I did not use a Goldap here but a 3V button cell battery that I took from an old pc mainboard, including the battery holder.
On his nice cloak he got some fluorescent pieces ... sadly this can not be seen on the video ...
On the top of his head he has what we call "RÃ¤ucherhÃ¼tchen" in German. I don't know what this is calle d in English, maybe one of you can help me.
Sadly also the smoke cannot be seen on the video and it is really loss that videos don't smell :-)
