Now I'm not talking about whistling in a vacuum. It's obvious that attempting to do so would fail. But even astronauts on spacewalks in protective suits can't whistle. Why not? Former astronaut Dan Barry explained:

"You can't whistle because the air pressure in the suit is only 4.3 [pounds per square inch], and normal atmospheric pressure is 14.7 psi, so there are not enough air molecules blowing by your lips to make a sound," he said.[...]
Jeff Hoffman, a retired astronaut with three spacewalks (including a mission to repair the Hubble telescope) has traveled 21.5 million miles in space. He said the technicians who trained him on spacewalks had told him that he wouldn't be able to whistle, but he says he tried anyway.
"I couldn't get one note out," he said.

I've said this before but I'm done with neatorama and this time I'm going to make a conscious effort to stop visiting. I don't know what happened over the last year but there has been constant bs, unchecked opinions or irrelevant expansions of generally known facts.
Oh, and has anyone else noticed the factless politics creeping in here? http://www.neatorama.com/2011/07/12/tea-party-to-save-the-incandescent-light-bulb/ I thought one of neatoramas pledges was to exclude political opinions.
If a student was in science class and asked "So, you can't hear them scream in space but can you hear them whistle?" they would most likely get a smart ass remark for their smart ass question.
I encourage others to do the same and check back in a month to see if they get the point.
This used to be the first sight I checked when I got online, now it's 6th or 7th because of crap like this.
Bring back the ability to vote for submitted links because y'all suck at it!
I've still never seen one of those $100 computers that were supposed to take over the world a few years ago.
The last time I checked it's about 350 for the two.
This on the other hand will blow up in price if, and that's a big if, it comes to the states.
Sad.
It may go the way of the Indian Tata as far as the price going out of reach of those who really need it after the safety commission and good old american import/export taxation.
Just like the OLPC fiasco - first it was $50/ea then when the prototype was released it was $99/each and then reality set in and it's a $250 piece-o-crap that nobody wants and can easily be replaced by numerous Netbooks off the shelf at Walmart for less money.
Besides - there are more studies showing that technology interferes with learning then there are that shows it helps.
