Heat tape is making my fingers tingle. Question!

lol try touching both clamps at once...it'll give you a little more than a tingle. Trust me I tried it a few years back, fun stuff haha. But forreal, cover the connections with electrical tape. Don't cover your flexwatt with it, just the connections. And Kaorte is right, aluminum is conductive because it's a metal (imagine sticking a fork into a socket, not saying you will get shocked badly like that, just think of the fact that you CAN get shocked simply by touching the metal)
