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.
