Aloha,

I have a wild guess for the mystery item.... It looks like a really high
tech cloud chamber. ( based on the cheap ones I have used -this is my
perdiction)
The radioactive source goes in the stopper (usually in the eye of a large
needle. The felt is soaked in alcohol and dry ice goes on or under the
apparatus . The cyliner/ tube is the viewing plan..with a dark bottom to
see the alpha particle trial as it goes through the cloud of CO2 gas.
Maybe the leads hooks up to a geiger counter...

or maybe I stayed up too late looking at Mars through the palm trees here in
Hawaii...

Guess when I should be sleeping,
Gail
