The Boston JCC  called me looking for maker activities for an upcoming Hanukkah event, and I thought of this little activity.

The copper tape is pretty unreliable though, and it may not be suitable for a big crowd where there may not be time to debug. I’d be curious to hear of other people’s experience doing paper circuits and the like. This was working perfectly for a while and then it stopped. I suspect the adhesive (which is supposed to be conductive), just stopped conducting. Perhaps I just need to buy higher quality copper tape?
