Happy Birthday ChiKat!
It seems totally unfair to me Perkins.
Betsy, thanks for that Science Fair link. Brendon is done for this year, haven't heard about Bobby yet. But yes indeed next year we will do it again. I'm jealous that your kid did actual science. The only way I could even get Brendon to show any enthusiasm was to let him burn up stuff.
That part was rather fun. The first trial the flame was too far away and it took too long for anything to burn. The second trial everything caught almost immediately with flame all over the place and the holders melting and all kinds of fun. We have pictures that we put on the board. The next few times we hit a happy medium.
Wow, there are divers who can hold their breath for almost
ten minutes!
I had no idea people could hold their breath for that long - I thought the max was 2.5 to 3 minutes.

Another volunteer diver, Tanya Streeter, dove to a record depth of 400 feet in 2003 and returned on a single breath. She descended on a weighted sled to a point about as deep as a 35-story building is high, and resurfaced with the help of a balloon.
Fun.
They do use tricks, like hyperventilating first.
OK, maybe that underwater scene in
Alien: Resurrection
wasn't so lame....
eta:
Prior to this year, I had probably never swum below 20ft while holding my breath. I would have never thought that I could ever swim down over 100ft on a single breath of air. With adequate training, it is within reach and can be done safely.
An important part of the training is in invoking the mammalian dive reflex, one that every human inherited from their evolutionary ancestors. This reflex allows one to significantly lower their heart rate (bradycardia), shift their blood flow to the core (blood shunt) and even reduce lung compression effects at great depths (thoracic filling). In addition, the training emphasizes significant physical, physiological and psychological tolerance as well as physical conditioning.
More fun.

t /saw GoF on Saturday
Happy birthday, ChiKat!!
juliana, your "Beep Me" post was lovely. Shana Tova!
(Which is Hebrew for "good year". Your post reminded me so much of how I see the beginning of the Jewish year. Also, we say "let one year end with its curses and a new year begin with its blessings". This is what I wish for you now.)
[Edited to spell Hebrew-in-English properly]
Happy birthday, ChiKat!!
Best wishes to juliana. Which sounds lame like that, but it's true -- I know you have many good things in your future, and hope for the best for you.
Can anyone explain why I fully blew off schoolwork ALL WEEKEND, and then got stressed out about it at 2 o'clock last night? I mean, honestly. I couldn't have done that earlier, when there was time to actually do something about it?
Happy birthday ChiKat!
May this be the most amazing year , Juliana!
and I was awake at the same hour Perkins posted. I just stayed in bed 'til 7.

Um, because you're human?
Jessica, first, happy third-day-of-your-new-age! Second, how did you like GoF?
Thank you, all.

I will remember "Shana Tova" for next year, especially since your Yom Kippur posts were the inspiration for mine. Thank you.
juliana, did you see my edit? I can't spell Hebrew-in-English properly! It's "Shana Tova".
And thanks.
