;-)

10 degrees is probably not far off. To do this right you would need to find a 
hot plate that you could take out to the garage so the water would actually be 
boiling while you read the gauge.

You could even start with hot water in a tin can, and keep it boiling with a 
propane torch while you read the gauge.
