NOTE: With the economy as it is, the HBD is struggling to 
meet its meager operating expenses of approximately $3400
per year. If less than half of those currently directly
subscribed to the HBD sent in a mere $5.00, the HBD would
be able to easily meet its annual expenses, with room to 
spare for next year. Please consider it.

As always, donors and donations are publicly acknowledged
and accounted for on the HBD web page. THank you

Subject: Bubble Logger [SEC=UNCLASSIFIED]

My dear Bwian,
Would elevation impact on the formation and frequency of bubbles?  My home is some 600 metres above sea level and I've also studiously noted that the thermometer does not read 100C when the boil starts!  I've noted (and unfortunately not had the foresight to keep a log of) a slight differential between boiling the wort when I'm located on the downstairs pool deck, during a nice sunny day, compared to boiling the wort upstairs in the kitchen when the weather is inclement.

If an online bubble logger could be developed, brewers all over the world could contribute data which I'm sure would be of assistance to somebody who needs a statistically significant sample - especially if the contributors qualified their data with the elevation of their ISO Standard airlock at the time.

But how do we cater for those of us in the first world who brew in metric and make 23 litre batches???
