[sudoroom] Ferro Fluids?

[Tracy Jacobs]

Hi,

I was wondering if anyone would be interested in doing some  
experimentation with Ferro fluids as a group project?  If we get nice  
results we could put them in the box office next Art Murmur.  I've  
been wanting to try that for a long time, and there are some methods  
that are free or under ten dollars cheap.
