ArticWave anyone?

If I could invent anything, it would be something the complete opposite of a microwave. By that, I mean instead of heating up something in seconds, it will turn cold in seconds, and if you're daring, you can even freeze in just minutes. Seriously, how nice would that be?

I know the fridge/freezer does the job for you already, but does it really have to take so dang long? Sometimes I want to semi-freeze a cup of orange juice, that its hard on the edge but smoothie like in the middle. Oh yum. But no, I have to put it in the freezer and wait a good three or so hours. Maybe more, maybe less. Sometimes I'll forget about it until the next day and by then it's just a piece of orange ice. It's still tasty, but not the way I want it.

I bet I would become a bazillionaire if I did this. (One can only dream, because I have no idea how I would even invent this brilliant product). And I would call it the "ArticWave". If anyone does actually invent this, I should at least receive 1% of the profit just for coming up with the awesome name. I could possibly be a millionaire instead, and I'm totally okay with that.

If you could invent anything, would would it be?
