Off topic...but for all you (science ) teachers....
 

It is -35 where my daughter lives at the moment...she just sent me a video of herself and the 2 kids outside... bundled up of course...and took a pan with a long handle of boiling water out there with them...and threw it up in the air where it instantly turned to "snow"!

My kids have been doing and enjoying it since morning..it is quite a bit of fun for them. The temperatures are so low in our area...

I've done that when it was -50ish (C/F is the same -40 I think), did it with boiling water even. I have seen -72 with the windchill.

Oh have them blow bubbles and see what happens :)

We do this stuff all the time when it gets this cold!

I used to do that as a kid - comes down as ice :)

OOOH! The bubble blowing sounds like a blast! Just talked to my daughter and she said it's been all over FB ...so since I am not a big FB person I guess I missed it! Anyway... it was terrific fun to see my granddaughters' reactions! The water WAS boiling...and it was a huge pan so there was no mistaking it...even watching on my little iPhone screen.

We are predicted to have a balmy 15 degree day here tomorrow...not sure with the wind chill what that will actually end up to be...but many of y'all are experiencing way w-a-y worse cold than what we are getting in suburban Philadelphia and the Chesapeake Bay area. However..after a certain point it's moot I guess...It's just too cold! Good days to make pots of IP chili...soups and drink a lot of tea. I stayed at the gym 2 hrs this AM because I did not want t go back out! The owner said..."Boy Kathie...you are really doing a lot here today"...LOL...the gym was a preferable option...even after having finished what I'd set out to do!By the way Sarabell...congrats on Onderland...happy way to start the NY!
