I’ve been curious about this for some time now. You know those weird electrical devices that you sometimes see in cheesy Sci-Fi films from the 50’s? It’s basically some kind of a box with two long metal rods (electrodes?) sticking out in a v-shape like a pair of rabbit-ear antennae on a TV. When you turn it on, an electrical spark arcs between the two rods and rises to the top with that familiar buzzing sound.
You pull the antenna off, slip each one thru the ends of a weenie and stick it on. If you slide the weenie up the antennae to the correct tension, it will cook the most disgusting hot dog you ever tasted.
Other than that, they’re useless. And its law that you must accompany the public use of any Jacob’s ladder with a theramin.
I wish i was able to take pictures of the one we made in school in mr k’s class in the physics lab I think Miguel took pictures of it when we set it up in the multi purpose room Maybe ask mig to post it.
We used a 100000 Volt Step up transformer and 2 1/2" copper bars and built it. Was really sweet too.
