Explain the physics behind Graham Effect seen in this video?

Question

I found this video, can be seen here http://www.metacafe.com/watch/718152/how_to_turn_water_into_ice_in_seconds/,
that freezes a cup of water almost instantaneously. One of the posted comments explains the phenomenon, allegedly called Graham Shrinder Effect, but is not very clear. Is this something bogus or does the explanation make sense to anyone? It mentions this "deromindal corpus attraction" that I could find no reference of. Thanks.

I know that salt solute in a solution can lower the freezing point and is a trick used to chill a bucket of ice water quickly, but how does this burned straw quick achieve almost instantaneous freezing of water?

Answer 1

im not positive...but i think its fake

that or its almost freezing and the salt raised its freezing point

Answer 2

Not only is that video a complete fake (it's obviously stop-motion or computer-edited), but the physics explanation given in the user comments is utterly bogus. The comment says:

"When the molecular atoms are excited by the heat or warmth emanating from the straw, it creates a deromindal corpus attraction which lowers the freezing point of the water tremendously causing it to freeze!"

1. All the atoms in water are "molecular" (part of a molecule). This is a meaningless phrase.

2. The straw stores only a tiny amount of heat, and this is quickly dissipated when the straw is put into the water.

3. "Corpus" means "body", and "deromindal" is total gibberish. There is no such thing as a deromindal corpus attraction.

4. If the freezing point of the water was lowered, you'd need a LOWER temperature to freeze it. That is, it would be harder to freeze it, not easier.

In short, it's a complete hoax. There is nothing real going on here. There's only video magic.

Answer 3

The salt straw and lighter are just distractions. The only thing you need for this is a glass of water, an unheated room during a very cold winter, and a time lapse camera. The freezing took place normally, he just sped up the movie. That's why you see the lighting shift, it's from the sun moving.

Answer 4

It doesn't. It's a hoax using trick photography. Notice how fast the light is changing in the background in the second part of the video. Also notice that the drop of water goes up, not down. This part is shown in reverse.

The second part of the video is a speeded-up view of ice melting that is then reversed. The first part is just to make it look real.

Answer 5

Bogus

Super cooled water will freeze, but all the mumbo jumbo is just that, mumbo jumbo.

Author explains the "change in lighting" as due to the ice forming, but the change occurs before the freezing begins - highly suspect

Answer 6

Hoax,

Watch the lighting in the back ground.
