Non-Newtonian Bed
Like a water bed, but using a non-Newtonian solution instead of water for better support | |
You just got home from a long, hard day at work. The boss has been riding your tail and all you want is to flop on your bed and pass right out. You kick off your shoes and fall gracelessly into your expensive fancy waterbed, which subsequently moves for ten minutes.
[Enter the Non-Newtonian Waterbed.]
You
just got home from a long, hard day at work. You kick off your shoes and fall gracelessly into your expensive fancy Non Newtonian waterbed, and it instantly reacts with firm support of your weight. As you relax on the bed, the patented "soliquid" yields to your weight, and allows you to drift off into a deep, deserved slumber.
As you shift your weight in the night, the NNWB will become slightly more firm to facilitate ease-of-movement and cut down on the incessant waves of a normal waterbed . . . as soon as you stop moving, it will resume cradling you in a pocket of soft liquidiness.

many newtonian waterbeds have baffles

If water were to be used, could baffles not be moulded into the plastic / rubber of the bed to cut damp out vibration more rapidly? |
|
| |
but i like the water bed ovements |
|
| |
[davidscothern] I agree that baffles would provide a significant dampening effect to the wave motion, but I don't know if they could be incorporated in such a way as to provide as much asymptotic resistance to force as a variably solid liquid. |
|
| |
Oh yeah, and I'm not a physicist, engineer, or chemist. :-) |
|
| |
No, I agree with you, a non-newtonian fluid would probably do a much better job. I was just thinking of a cheaper interim measure, but it seems that this is by no means an original thought (FJ's link) |
|
| |
Genius! My bed squeaks like a squeaky thing, which means any, er, energetic activity generally dissolves into giggles. This would be perfect! The material would need to be very non-newtonian, but bypassing all those squeaky springs during sex would be a godsend! |
|

You could be evil and fill the bed with a
thick mix of cornstarch in water, which
has inverse thixotropy (it locks solid
against sudden movements, but flows
like a liquid when left undisturbed).
Under this scenario, you kick off your
shoes and fall gracelessly into your
home-made Non Newtonian waterbed.
Instantly, you find you've fractured your
collarbone against the concrete-like
surface, which then yields squishily so
that you can enjoy the pain in comfort.
It'd be good for sex though (the faster
you go, the harder it gets.....) |
|
| |
Yeah, uhm . . . that's the design. The mixture would be weighted such that instead of becoming a rigid solid, it merely firms. Bleach (or similar) added to keep the nasties from mouldering. |
|
| |
Ah - I see. By the way, is there a term
for 'inverse thixotropy' rather than
'inverse thixotropy'? I have a feeling
there ought to be... |
|
| |
Counterintuitive viscous physics? I believe that a "non-newtonian solution" distinctly implies a 'liquid' that has inverse thixotropy. |
|
| |
Did Newton invent the water bed? |
|
| |
A thought: If you were to create a non-newtonian waterbed surely you'd have a problem whereby once you stopped moving you'd sink into the liquid and either a) drown, or b) have a real problem getting out, as trying to pull yourself out of the liquid would cause it to solidify around you? (This affect was demonstrated on Brainiac recently when Jon Tickle walked across a swimming pool of custard, and then sank when he stopped - getting out again was not at all easy). |
|
| |
I think I suggested toothpaste last time... |
|
| |
[RR], it would be encased in plastic . . . :-) |
|
| |
[contracts] - a non-Newtonian liquid is
(I'm told) any liquid whose viscosity
changes when it is stirred, but the
change can be either up or down. So, a
thixotropic liquid (like non-drip paint)
is a n-N liquid whose viscosity drops on
stirring, but there seems to be no
specific term for a n-N fluid whose
viscosity increases on stirring (except
for 'inversely thixotropic'). Which is a
pity. |

//"soliquid"//
Liquid crystals? |
|
| |
// it would be encased in plastic . . . :-) // |
|
| |
THAT makes more sense..... ;) |
|
| |
That makes more sense than "Like a water bed, but using a non-Newtonian solution instead of water for better support" ? |
|
| |
// Did Newton invent the water bed? // |
|
| |
Obviously. How else do you think he discovered gravity? |
|
| |
He also invented the shoe horn, the cat flap, the spoon, and the spectrums of Venus. |
|
| |
[Basepair] I've seen the term dilatant in elsewhere on halfbakery. |
|
| |
[Caspian] - I just did a Google search
and you were right about dilatant.
Thanks :-) |
|
| |
I want one of these, right now! |
|
| |
The cornstarch 'fingers' on [5th Earth]'s link is entirely disturbing. Please don't give me the non-newtonian bed with that feature please :D |
|
| |
Can I give this one 2 pastries? |
