..this guy moves like a demonstrator for the shopping channel...

Pretty awesome.

This video proves that astronauts are the biggest nerds ever. I love it.

Batman's a scientist

Would this still work with Heavy Metal?

Why do they have CD players in the first place?

This looks like serious research.

*sigh*

The future of space-flight anti-oscillating meal trays is today! No more messy spills!

stephen - I wondered that. Hasn't NASA heard of mp3 players? At a fraction of the weight.

Mammy? I want to be a scientist

I have no idea what he was getting at. It's like coming in at the middle of a movie or lecture.

I could understand if they were using CDs as a recording medium for some of their work, but I think MP3 players would be just as simple.

MP3 players for astronauts

Our tax dollars hard at work. End the space program now. Privatize it and really kick start the economy.

Its called science and just because you don't understand the usefulness of these goofy little experiments doesn't mean they don't have significance to us engineers. The space program is prob one of the most important things humans have ever done.

There are some brilliant comments about how this is "great research" and our "tax dollars hard at work." I would like to point out that, yes, astronauts can only do one thing all day. This 5 minute video did, in fact, consume an entire day's worth of work and nothing else was accomplished. I'm sure you spend every waking second working.

This video will probably be used in elementary schools all around the country and probably even in middle school science classes. This is a free video that can be used to demonstrate some interesting physics concepts using everyday materials that the students will be able to relate to. It's a great teaching tool and was probably put together after they finished the serious work.

What a great way to describe a "space clamp" - something which holds an object oriented in a certain direction while floating in microgravity. This is how spacecraft can point in one direction. Example: suppose you want an orbiting satellite (such as GPS) to always point down toward Earth. Spin the onboard gyroscopes. Voila! A "space clamp" to hold the thing pointing in one direction. You need an actual spinning disk to do this, by the way. Hardwired items such as memory sticks won't work...
