you can do anything if you put your mind to it.... maybe you can make a doom ray. if it actually can vaporise something, then i think theyll be forced to give you the reward

Any RAY that doesn't work properly is a doom ray (doomed to failure *sigh*)

Yes, that is what I was referring to. The mindset that all problems have solutions is a shortcut to madness.

I know I just like doom rays... Another quick and easy shortcut is to work in retail.

You don't want to, especially on a sunday, try 13hours of work after a night that left you completely off your face until about 12pm, that said the manager was in no better state.

Maybe a speaker with some sort of parabolic focusing array, so you can whisper directly into the ear of somebody across the room.

hovercraft were already invented. you still entered one. and if you desine the driver circuit yourself, your jacobs ladder circuit has been invented.

I've never seen a radio-controlled hover-tank, outside of sci-fi movies.
