As some of you know, Cracked has undertaken a project to show you all sorts of awesome yet deadly experiments people have done at home, specifically so you won't feel the need to do them yourselves. Please, enjoy the fruits of their labor and don't start taking apart your own microwave to see if you can build a railgun out of it.
After all, these bold-slash-insane experimenters risked serious injury or death to bring you...
You know what sucks about speakers? They rarely, if ever, kill anyone. So what if you wanted to blast your music and risk a horribly violent yet quick death? Some enterprising folks on YouTube have done that exact thing.
The guys building these online use PVC, some electronics and an MP3 player. Basic soldering skills and a knowledge of electronics also help, but when it comes to making horribly dangerous knick-knacks in the home, any kind of pertinent knowledge base can only hinder your success.
It turns out that taking the electrical signal that would normally be used by a speaker and arcing it through the air not only produces sound, but makes it clearer than conventional speakers. The discharge moves air molecules, just like a traditional magnetic speaker. Only if you bump into it, you may never grow nut-hair again. So there's that.
