Waterbed of Doom

It just straight-up kills you for non-polyphasic sleep
  [vote for,

Have you ever tried to have one of those fancy sleep cycles where you sleep for half an hour, six times a day? Have you found it simply too hard to sleep for only half an hour? Well, nothing will make you get out of bed on time like a bed that slowly smothers you if you stay in it too long.

All you need is to use a full water bed as the mattress, and an empty water bed as the blanket, the two waterbeds connected by a hose. As long as you are between the two waterbeds, water will be forced into the upper waterbed, giving you limited time until you're trapped and can only wait to be slowly smothered to death.

That'll make you sleep polyphasically.

       Uh, well, yes.   

       This is quite ingenious, and clearly solves a much-needed problem.   

       Welcome to the Halfbakery - emergency exits are located over the engine intakes to the left and right.

       Welcome to the Halfbakery and may God have mercy on your soul.

       Pretty sure they already sell this at Walmart. They call it Polyphasic Watercouch Of Death but it's basically the same thing. [+] Greeting bun for the newbie.

       // may God have mercy on your soul. //   

       1. There's very probably no God.   

       2. Check your soul at the door. You'll need a quarter for the locker.   

       We like the idea. Could it be adapted to attract cats ... ?

       Some heating elements in the water would cause it to come to the boil, then you could use the hot water to make a nice cup of tea in the morning.

       I wonder if the "...of doom" suffix will affect the marketing of this product...

Welcome to the Halfbakery!

       Won't work unless your mattress is filled with mercury. You might not be able to move but breathing shouldn't be too much of a chore.

       Dangerous, unnecessary and leaky; an excellent start. [+]
