Simple question, are breasts bouyant at all? My colleague at work claims his large breasted wifes breasts are bouyant and I wasn’t sure why they would be. Anyone know?
I don’t have any special knowledge, but why would that be surprising? People are buoyant.
Depends on the breasts, but since most are high in fatty tissue, they are less dense than water; ergo, they float.
Everything is buoyant, in the sense that they weighs less in water than in air. So everything sags less. Doesn’t necessarily mean it’s lighter than water.
I don’t think I’ve ever noticed them to be particularly buoyant. I own a pair, and I can say that when I stand in a swimming pool they don’t feel particularly more lifty-uppy as compared to the rest of my body. The whole body is really a bit more supported and floaty when in water.
Fat isn’t very dense, but by that logic a beer gut should float too. Any takers?
If everything qualifies for that sense of the word, it’s not a very useful sense, is it? 
He made the claim that they float up under her chin ‘like water wings’. I can’t see why breasts would be anymore bouyant than say an ass cheek or a beer belly. Her breasts are real by the way so its nothing to do with that.
Yes, it is. The precise definition of buoyancy is the mass of the object in air minus the mass of the water the object displaces. So, even though a hunk of steel sinks in water, it is nevertheless lighter by the mass of the water it displaces.
I knew that of course. But, for instance, in classical physics, everything has a mass, so technically everything is “massive”. But that’s not a useful sense of the word “massive”, and that’s not what people mean when they use it. They mean having a large mass. So it is with “buoyant”. The OP was clearly not asking about anything being buoyant in scr4’s sense of the word, but rather in the sense that most people use it, “able to remain afloat in a liquid.” (Dictionary.com)
Now you’re just being silly, Achernar. Just because most people don’t understand the correct usage of a term doesn’t making doing so “useless”. The correct definition of “buoyant” is perfectly useful. Proper usage is only useless to the ignorant.
I needed to adjust my swimsuit top in the hot tub back at stately Mercotan Manor once, and since I was alone and it was dark, I just popped it off quickly. There was noticeable floating. Kind of cool, actually.
I’m sure you know what I mean by bouyant…do tits float? Any clearer?
Q.E.D., I will be quite surprised if you can find any sort of reference that uses the term “buoyant”, referring to an object, to mean “displacing a positive mass of fluid”. Nobody uses the adjective like that, even people who use “buoyancy” to mean what you consider the correct usage. Everyone who talks of a buoyant object means an object which floats.
Sorry for my sloppy choice of words. What I wanted to say is: I don’t know if the actual breat tissue is heavier or lighter than water, but even if they are heavier, they will weigh much less in water than in air. So when you step into a hot tub, they will rise up higher. Same will happen to a flaccid penis.
:smack: Ack, I’m sorry. That makes sense. I thought you were trying to make a silly semantic point. Nevermind me.
Of course breasts aren’t boyant. They’re girlyant. Duh. 
I can find hundreds. But, don’t take my word for it. Google the phrases “positively buoyant”, “negatively buoyant” and “neutrally buoyant” and you’ll find a whole bunch of hits all using the term “buoyant” in just exactly the sense I was talking about.
Simple, your colleague’s wife has implants.
Here’s a website where an engineer measured the density of an implant and found it to be .962 g/cc. It should be noted that the implant floated when he made his measurement of water displacement.
The specific gravity of the whole body, even for the skinny, is very close to 1. When I only weight 140 lb. at 5’-8 or 9" I could float on my back in a still, indoor pool. When I inhaled I would slowly rise so that most of my face down to the chin-neck junction was out of the water. When I exhaled I would sink down until just the tip of my chin, mouth, cheeks, nose and forehead were out.
As someone said breasts contain quite a lot of fat so breasts should be somewhat less dense than muscle tissue and would probably tend to float.
An ex-girfriend who was (still is) extremely gifted (naturally so) in the breast department has reported to me on more than one occasion that her breasts float when she goes hottubbing naked.
