You slip and bump your head on your bathroom sink, and suddenly you have the most amazing idea. You retreat to your basement and spend 24 hours building a crazy device out of household electronics, and when it’s finished your head is still clearing–you don’t even know what it is.
When you emerge with it the next day, you quickly discover that you’ve just build a mind-control device. When you speak through it, you can get people to do just what you want them to do, and they’re happy about it.
An amazing discovery! But could you make someone kill themselves, or kill others? How long does the effect last? You don’t know the answer to that.
How are you going to test the limits of your new device? And what are you going to do with it?
