back to article Just in time for summer boozing: Boffins smash world record for the most perfect ice cubes

An international team of chemists has set the new record for crafting near-perfect cubic ice crystals. Sadly, the ice cubes are so small, they are invisible to the naked eye. This is according to a study in The Journal of Physical Chemistry. It might sound trivial, but it is an extremely difficult task – one that involves …

    So if they get the cubic versions big enough to be visible, are they going to keep my margarita from melting as fast?

    Why is ice slippery? It isn't a liquid - unless it momentarily melts with friction. Made of hexagons one might have expected a relatively rough molecular surface?

      Apparently it is a liquid, well a thin layer on the surface is.

    I also remember reading how ice and water generally has some of the weirdest properties of pretty much anything. Make water a solid and it gets larger not smaller and thats just the tip of the iceberg...Ah. I'll get my coat.

    That's a -48c super cooling. Astonishing. Possibly with major effects on climate models

    So small crystals may have a very large impact on human understanding.

        Not in a proper single malt you can't, but it enhances a crappy scotch (you know who you are...) and makes it almost drinkable.

      I've heard it both ways, and another interesting addition of just a few drops of water. Something reacting something... I'm no chemist.

      Scotch on the rocks is for people who drink it a lot and a lot of it. I prefer only one per evening. Just like only one glass of Champagne... Too much of a good thing ruins it..

        "[...] and another interesting addition of just a few drops of water."

        In school physics we were taught that two equal volumes of liquids occupy twice the space. Later on we were told that an exception is alcohol and water. Their molecules fit together to occupy less than their expected space. It is very difficult to distil pure alcohol because of their affinity for each other.

        Apparently adding water to an alcoholic drink makes the human body absorb it more effectively. A watered down drink makes you drunk faster.

        Antifreeze (glycol) is interesting. As you mix it with water the freezing point decreases - until a critical point is reached after which it increases. This an example of a eutectic curve.

        It seems that for every real world rule of physics - there is always a limiting case where it no longer applies.

        Re: most perfect

        In this case it is not a range of perfection that is being stipulated, but an amount relative to other efforts. The scientists created more examples or a greater percentage of perfect ice cubes than previous groups have.

    I've read too many papers with the word could thrown about. Sometimes, they even use could potentially, and then you know it's even more far-fetched.

    "to probe the atomic structure of the droplets"

    I'm pretty sure that's not what they were doing.

    In this case atoms, molecules and crystals are all different things.

    And x-ray diffraction isn't great at probing atomic structure anyway.

    First time I saw a moon dog

    I'm a rational man. I follow the scientific method. However, the first time I saw a moon dog, with a full moon centred within a giant glowing ring, like a giant cosmic eye staring directly at me - I completely understand how people believed in gods.

    Halos from cubic ice? Rly?

    You write:

    "Scientists think cubic ice may be responsible for creating light halos that are sometimes visible around the Sun, as the sunlight is reflected from the clouds."

    Most haloes are caused by refraction rather than reflection. Although it is true that a very rare halo display seen in Chile has been explained by the presence of cubic crystals (see https://doi.org/10.1364/AO.39.006080 ) , most of them (including all the ones in your picture) can be explained by ordinary hexagonal ice. Readers who want to waste a LOT of time looking at pretty pictures of haloes can head over to http://www.atoptics.co.uk/halosim.htm

      Re: Reminds me of...

      For clear ice, (if memory serves) the trick is to freeze it slowly, like around 0 to -1 Celsius. This gives the ice crystals (hexagonal) a chance push the air out of solution, rather than trapping it in suspension.

      Slow freezing is also a good way to freeze-distill (jack) wine/cider, as the crystals will also push the ethanol out of solution.
