Hi Jerry,

I've actually seen these types of devices in the section where Walmart
has lamps.....they had various types of different sizes, and even one
which was a night light.

Haven't been there in a while, but you may want to check there, or a
similar place like K-mart.

Could you just make one with a tall beaker, magnetic stirrer, and
rheoscopic fluid/beads?


Who was at the O's-Rangers game(s) yesterday with my son.....30-3.....yikes!
At least it was cool 65 degrees...Baltimore in August? NOT!
