Its just an estimate of weight and IMO a very good one, don`t take it too seriously. So Grim, instead of just saying "the TRUE mass would be less than your estimate.", which is next to useless, give your own calculated estimate of weight. I did at least have a good try.
AND Grim, unless you never read my post properly, I did allow a generous 50% air content. The density of ice is absolutely nothing whatsoever to do with snowflakes.
You cannot have a common density for a snowflake, which is not solid ice, too many variables. A snowflake is comprised of a complex and integrated web structure of ice crystals and air. Which my dear Grim is why I made a rough guess of allowing a 50% air mix. So your 0.92 x water density for ice is of no interest at all.
Oh come off it Grim and enjoy the party, it is just a bit of scientific fun, not an examination.
Even half my estimated weight if it makes you ecstatic, would mean that 10 lbs. falling from around 2,000 feet or so would give you one almighty big clonk.
Example - a skydiver descends at about 124 mph in full spread. A 21 lb. weight would descend at very near the same speed.
Although records are records, a fragile ice/air mass of 21 lb. falling at about 100 mph must shatter to pieces on impact. I cannot understand how they measured this record breaking snowflakes size when shattering on impact is certain. Sounds like a 19th Century leg-pull to me.

Wow, someone's a bit touchy this morning. Reading your post makes me think you're the one that needs to kick back and join the party.
I was just pointing out your fundamental error. If you make 'statements' on a forum then you need to understand there is a kind of peer review from people who will always be cleverer or more knowledgeable than you.
I did assume that you were trying to be accurate by your use of three decimal places but obviously not.
Maybe I should have said something along the lines of wow what a scientifically accurate post BUT saying things like that is how things like
this happen.
One last thing - my friends call me Grim, you can call me Mr North
.
Cheers
Grim
