ok, someone explain this to me.

my roommate made an art project of filling up condoms with plaster of paris. she was going for some dick looking things or something, who knows.

anyhow, she filled the condoms up, tried hanging them up but they started ripping. so she gave up, tied the rest of them like a baloon, and hoped for the best.

we both thought there would be no way in hell they would dry, since no air was able to hit them.

well, this was around midnight last night, and when i went outside on our deck, i picked one up, and sure enough it dried completely, even though it was encased in a latex condom and had the open end tied off completely.

how did that happen? the moisture had to go somewhere....and even if the condom had tiny, microscopic holes in it, i still dont see how it could dry in less than 8 hours.

I think PoP goes through some sort of chemical process where the water actually combines with the other ingredients to form something else.


edit: technically speaking, that is.

I don't know for sure but isn't water vapor a LOT smaller than semen.

Think about Gore-Tex. No water will penetrate but water vapor has no problem with it.

I may be dead wrong but that's the first thing that came to mind.

couldnt various viruses pass through the latex then?

Unless you guys performed this experiment in a vacuum....air was involved.....and apparently enough to act as a catalyst for the reaction that bonded the agent.

Not a bad explanation after several vodka's....ahh, who knows...it was magic!

The gases could've escaped through the end that was tied... that's only a micron or two, so gases can exit there.

You will notice, if you had picked it up in the middle of the process that the PoP was warm. For quite a length of time. This is the chemical processes re-combining the various chemicals into more stable or just plain different compounds. Concrete is the same way.

In addition . . . condoms are not designed for the indefinite retention of seminal fluid, blood, or any other fluid. It is temporary, not permanent. You will notice that the packages make mention of not leaving it in the female too long after you are finished. The are pores that can be large enough to pass sperm, not in quantity . . . but it only takes one determined little guy to ruin your whole college experience.

Plaster doesn't dry so much as it cures. It gets warm as it dries. It will even harden under water.

The hemihydrate of Calcium Sulfate is Plaster of Paris. If exposed to additional water, it will aborb it and solidify. Air has absolutely nothing to do with the reaction. The condoms are working just fine.

Regardless of the chemical process of plaster curing (which does tie the water up), latex condoms are a semi-permeable membrane (just like most plastics). Given time, water will escape through the ultramicroscopic pores in between the polymer chains. Same for plastic soda bottles. Eventually a 2-liter of soda, unopened, will go flat due to the carbon dioxide gas diffusing through the bottle wall.

Doesn't concrete need air? I remember reading about some large dam (might have been Hoover) where they had to put pipes though it to run air though so the thing would dry.

the pipes were filled with water and were used for cooling the concrete as it dried. that much concrete creates way too much heat!!

Cement and plaster of paris don't dry... they "cure". The water combines with the various calcium and aluminum silicates, to form a crystaline network, known as "water of crystalization".

Ever seen "bluestone"? Copper sulfate crystals. These blue rocks, or crystals have water as part of the crystalline structure, but if you heat the crystal it falls apart to a white powder. You have driven out the water of crystalization. You can do the same with cement.

So, yes, cement will set up underwater, as will plaster of paris. Plaster of paris is sometimes combined with cement for some very quick set cement formulations.

This experiment clearly shows that instead of using a condom before sex, you
should instead, plaster of Paris your dick for better results.

1) Latex rips. Think rubber glove, but thinner.

2) Latex is porous. Not porous enough for sperm to get thru, but porous enough for some biological contaminants...

Condoms are effective against pregnancy, but are only partially effective against getting sick...

That can be your story next time you're piss drunk and trying to bang some skank bareback.


Reminds me my roomate in college trying to bang a chick in my room one night. He got some skank to fuck him and took her to my room. He grabbed the bottle off the night stand to use as lube in the dark - he thought it was hand lotion or something. It was actually one of the red plastic bottles they used to sell of............Old Spice! That shit was like 50% alcohol. He said his dick was on fire for about an hour. Needless to say he never did seal the deal.

Mine has hardened underwater. In fact, many times in the pool in my backyard.

Latex does have holes in it. My high school biology teacher explained to us that 10 AIDS virii stacked side by side could pass through the holes in latex without problem. Notice how a latex balloon will deflate over a period of days after being filled with air.

Plaster of paris cures by an exothermic chemical reaction. Air has nothing to do with it.

Remember the Alamo, and God Bless Texas...
