Hey guys I have a story for that one... I was bored one night and I took of the speaker for this big toy we had. Place it face down on my desk and parted the wires.
I then found all the batteries we had in our house. I forgot how many of what since I was like 12 then, but I made this big half-circle consisting of about 4 D'*, 3 C'*, 6 double-A'*, and 4 Triple-A'*. I put them on my desk touching tips like I said in a half circle and then put one wire to one end of the circuit and then the other onto the opposite end.
At first there was nothing, then I started to hear the sound coming into our human range of hearing, then it started to get really really loud and then the speaker started jumping a bit and it was smoking out the bottom! That'* when I pulled the wire away afraid it would leave a burned mark on my desk, haha.
Yeah I was one of those kids that went through a pyro phase. @_@
