There is only one way to ever truly know. It is a commonly known scientific fact (certainty dare I say!) that gay people are hydrophobic. As such, they float. Wood also floats. The only true way to find out if he is gay is to see if he is made of wood, by burning him. If he burns, hes gay!

They have a video of a hydrophilic ball and a hydrophobic, where the first creates almost no splash and the second creates a big splash (the second is shown in this sift).

Also, if you have access to article databases, here is the abstract for the source paper

Thanks for the sift, really interesting stuff.

I wonder if it's skin is dirtophobic too.

Actually, being hydrophobic will automatically make a material self-cleaning. The water will dissolve the dirt, and then just fall off. On a normal material the water would stick and evaporate away, leaving the dirt in place.

I found pricing between $75 and $120 per cubic centimetre. That may be why he has a slightly pained expression when he breaks a piece.

According to Cabot Corp, one of the manufacturers of aerogel, it is completely hydrophobic, so I would guess the deterrent from its use as a bath toy is cost...

Here's a 10-year-old who produced his own aerogels.

Long time lurker (2 years maybe?) but not a frequent commenter.
I have to say I agree with Gorillaman for the most part (even if his comments may seem kind of jerkish, but really, if we stop and think bout it objectively that should be irrelevant to logical discourse).

Even if America was 98% made up of overweight hydrophobic asthmatics, the result of this would have been the same as long as the Olympians came from the remaining 2%. THAT'S what his comment 'The US is not competing in the Olympics' means to me anyways. No Olympians from ANY country really represent their home. That being said though, if you ever dreamed of being an Olympic athlete (even if you're as out of shape and athletically challenged as I am), pride is due here because the bar has been raised for Olympic athletes everywhere. With that aside though, unless you came to America because of our Olympic teams, I don't see the point in pride in happening to be born in the country that has a couple dozen really skilled athletes competing right now.

Maybe it's just how I've been raised. My mother taught me well : be proud in what YOU do and don't do, feel shame for other things YOU don't, and do.

Pretty phenomenal. Swimming normally bores me, but the finals I have seen have been so close. The womens 400 (forget discipline) was another race where the leader had a metre or so distance between coming into the last 10m, and then just fell into silver. Also, that is an insane amount of time to be ahead of the world record. I wonder, are they going to train in the old suits and then put on the hydrophobic ones for competitions?

All the national pride does make me kinda uncomfortable Bad vibes I guess, but then this IS the Olympics. I just cheer for whoever is in first place.

"GOOOOO FRANCE......GO AMERICA YEAHHHHHHH!"

Soot is mostly carbon, and is highly hydrophobic (nonpolar). So, when you drop it in water, it is not "wet" by the water. What you get is a very thin layer of air trapped against the sooted eggshell. That's what is acting as a mirror.
