and they should have had sven. oh well!
never seen -51 before :O
It's -45f with the windchill right now.
The other day it was -61f with the windchill.
Perhaps the banana test should be the defining factor on closings...
Hot water trick is always fun
It sublimates. The hot liquid water breaks up into ice crystals and then much of that goes directly into a gas state. That part which doesn't falls as snow.
It's almost the same thing that happens when you hang wet clothes out in winter. They freeze, and then they dry as the ice goes from a solid directly to a gas without passing thru the water state.
Sublimation.
Neat huh?
