Hot and Cold.

Question: Can hot water freeze faster than cold water?

The answer is here.

Now it's your turn. Do you know any counter-intuitive facts?

Mmm... Well, I don't have any counter-intuitive facts, but I recently bought a book called A World of Imponderables that answers a lot of the really important questions... Like why is there no Betty Rumble character in the Flintstones Multivitamins, or why do paper bags have jagged edges, or even, how does the water keep from freezing in a water tower...

Do those count for anything? :o)

The more water you put onto a water slide actual slows a person down.

Water acts as a lubricant... unless there is to much water, then it acts as a dampening agent.

Um....

Remember the movie "Carrie" where she gets her period in the beginning and freaks out? Well, you probably know this, but in real life that wouldn't happen because the water from the shower would have kept her from flowing. I heard that somewhere.

That's all I got for ya, besides love.;)

Very intersting. I love watching the show Mythbusters and would love to see them do this experiment.

Rt, why isn't Betty in the Flinstones vitamins? I have always wondered that one.

I had always thought that this was an "old wives tale". Interesting post.

Teri, it's because she isn't a popular enough character... Yep, you read that right, the Flintstone's car is more popular than Betty Rubble!

As a matter of fact, she's so unpopular, that I didn't even bother to spell her name right the first time, lol.

I wonder if the Mpemba effect is what causes some cooks to think the opposite is true... that cold water will boil faster than hot. I can't think of anything counter-intuitive at the moment. I like the Betty Rubble vitamin note, RT. I tend to look for those kind of things in packages.

Martin (80snut) did a post something about this one time.

Um, counter-intuive facts....

No, it's all you, V!

Wow, the Mpemba effect. I did an experiment to prove it. Took a glass of cold water and hot water and placed them outside under identicaly environmental conditions and the warm water froze first. Of course I followed the articles advice and did not use identical water samples in all regards except temperature. The cold water had salt added.

Of course, warm water can freeze faster than cold water if you don't control your variables. Not surprising at all.

I mean really the article says "The fact that hot water freezes faster than cold has been known for many centuries." Isn't that just a little bit deceptive? Why are you pointing to such an article as being scientifically accurate?

The Mpemba effect sounds like it is all about not controlling ones variables, or just plain old bad experimental results.
