Here's a neat trick on how to get a drink to be ice cold in just a minute using science! Check out the video - http://youtu.be/zIIsg-tXqEA

I call shenanigans. The ice was melted before salt was added. At that point, all you are doing is making salty water. The salt does not magically make the water colder.

This would be great with bottle conditioned beers. NOT

I call bull shenanigans. 

A miraculous technique for cooling a beverage in 10 seconds is to put ice in a glass and then pour the beverage over ice.

So the video is bad. However, isn't the theory correct? Lots of ice and water is very cold now add salt which lowers the freezing point of the water so the energy is not wasted in a state change but rather to cool the beverage with water that is now able to stay liquid at a lower temperature. Same theory as the old time ice cream makers we churned by hand during the summer. At least that's what I remember from school

Only way i know of cooling in seconds is sience called Glycol ...and thats.expensive equipment

Yes, but you need a lot of ice and a lot of salt to get a significant enough freezing point depression where you'd notice a difference over just plain ice water.

~10 % for 20 degree drop. http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/meltpt.html

[flynnale]

But yes the video is bunk

~10 % for 20 degree drop. http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/meltpt.html

So about 100 grams per liter. More, if you take into account for ice melting into solution and diluting it. And you need quite a bit of ice to be able to effectively drop the temperature of the brine.

But yes the video is bunk

Agreed, for reasons above

~10 % for 20 degree drop. http://hyperphysics.phy-astr.gsu.edu/hbase/chemical/meltpt.html

For a drop to 20°, not a 20° drop.

If you put a can in a good ice bath and keep them both moving to minimize temperature gradients, then can will cool in a minute or two without salt.
 
The video seems to suggest that salt added to plain water will miraculously chill it, since the cubes are melted by the time the salt is added - what a load of bunk.

I wonder if videos with correct science or painfully bad science get more clicks?

I think it depends on if the viewers also watch Fox News or CNN.

What if they dont watch either? Huh? Huh? Booyah!
