|    Foam rubber that will sink in water.    |
|    15 Dec 25 22:52:44    |
      From: NONONOmisc07@fmguy.com              K need something an inch, inch and a half, at most 2" thick which by its       nature won't float or which will fill with water and not float, which I       can sit on in the bathtub so that it not longer hurts to sit on thard       surface.              I'd also like to know if so-called AI is acting stupid again:              When I google foam rubber that will sink       so called AI says               "Key Factors for Sinking Foam:               Closed-Cell Structure: This means air pockets are sealed, making it       less permeable to water and air than open-cell foam, but still       compressible."              Isn't this backwards? If the cells are closed, they remain filled with       air, and the foam will float. Right?              It also says "Dense Upholstery Foam: Look for ratings like "1.2 Density"       or "33 lb Compression" (ILD), as these provide support and are less       airy." Do these 2 things sound correct?              If the foam becomes totally waterlogged, will the specific gravity still       make it float, beucas it's maybe 98% water and 2% foam rubber and the       foam rubber is lighter than water? or will it stay at whatever depth       its place, stay on the bottom if it's placed there?              Since I lost weight, 270 to 200 on a 5'8" frame, I've lost a lot more       weight in my butt than I had originally gained there, so it's less       resilient than any time in my life before, and it hurts to sit in the       bathtub or on a hard chair, or even some padded chairs.              I miss taking a long pleasant bath. I tried a piece of foam that they       sell to sit on in football stadiums and it floats. I can trap it but it       tends to escape, it's pretty inconvenient, and ii would be better if it       were thicker.              i found things for sale that are pre-weighted, but they are all 4.3 to 5       inches high and meant for hottubs so that women won't get their hair       wet. My bathtub is already too shallow, so I don't want to lose that       even if I were not fat at all, I can't get my whole chest underwater.       I don't want to lose 4+ inches even more depth.              I need something an inch, inch and a half, at most 2" which by its       nature won't float or which will fill with water and not float, but is       softer than steel.              Any ideas, products or materials, or suggestions?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
