Ever tried to explain...

I have a different one for you to ponder. I saw this phenomenon in Arkansas. It's called Frost Flowers. I was driving to a town early in the morning in the mountains and the temperature was in the teens. I kept seeing these white things in the ditch for miles. It looked to me like someone unstuffed a cotton pillow. I finally stopped and took the pictures below.



The temperature and humidity has to be just right for this to happen. As soon as the sun hits them they're gone.

I haven't heard the one about hot water freezing faster than cold water. That's funny.

Sunday I'm getting up early to boil some water and toss it up in the air on the patio. Its supposed to freeeze before it hits the ground when its really cold but I dont know what really cold needs to be for this to work.

I'm pretty sure it needs to be well into the negatives, but I don't remember. I do know that water will flash freeze at -39* (F or C) on Earth.

My 9th grade science teacher was from Wisconsin, and he told us about the winters up there. One of those stories was from when he was in military school, about how they'd open a second floor window and dump a bucket of hot water out so they could watch it freeze before it hit the ground.

@Snattlerake, the ice flower pics are really great. I've never seen that before.

IF you turn it around backwards, yes.
I used to be a builder and framing with metal studs, this is how we cut them. I recommend hearing protection though.

. Nope, we use them frontward just as if cutting wood.

Must be carbide
We didn't have that in 85

We always took a regular circular saw blade and turned it backwards to cut sheet iron but never tried it with anything thicker

I've seen this in N. central Lincoln county. It had formed around only one type of weed. My understanding is the conditions have to be just right.

I remember a neighbor doing this many years ago, and I can still remember the lovely sound.
