sundevil777 102 #1 February 10, 2007 I hadn't even heard of this cool fun that can be had in your own freezer! Growing Ice Spikes! How many of you have even seen this, not to mention know how it happens?People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am Quote Share this post Link to post Share on other sites

hookitt 1 #4 February 10, 2007 The urge to go buy distilled water and make some has just come upon me. I know how it works.

sundevil777 102 #5 February 10, 2007 I didn't do anything special besides put very clean water in a freezer that blows a lot of air around.

flygirl1 0 #13 February 10, 2007 Ok so I tried this last night because I can't ever refuse a good science project and I got one ice spike. Yes only one. I rinsed out the tray with distilled water, filled all the cubes up evenly with distilled water and only one grew I wonder why?Fly like a girl Quote Share this post Link to post Share on other sites
sundevil777 102 #14 February 11, 2007 I usually only get one, and not every time.

skydiver30960 0 #15 February 11, 2007 The reason is heterogenous vs. homogenous nucleation. Dig it? Back to my previous career: when something crystallizes (i.e. metals in my past career, ice in this case) it needs some place to get started. In normal tap water there are enough impurities bee-boppin' around to create a multitude of sites throughout the cube to start freezing, so it all happens (relatively) at once and ergo no spikes. With distilled water, there are no sites for this to happen because the water is (relatively) pure. Thus, freezing happens at the surface first because it's exposed to the colder air, except that once the water gets below a certain temp (something like four degrees celcius) it stops contracting and starts EXPANDING, sort of like pre-freezing. Thus, it punches through the frozen surface of the ice in one small spot and starts to grow the ice spike as described in the webpage referenced here. Why didn't your trays work? Mebbe they weren't clean enough, try cleaning them again. Are they old trays? Nicks or dings in the surface of the tray can act as nucleation sites, the same way a stream of bubbles always seems to come from one spot in your beer glass. Also, as the article mentions, temperature can play a factor, so mebbe fiddle with the thermostat in the freezer to see if you can find the sweet spot. And to think, I gave up all this to become a nurse. Elvisio "so much wasted knowledge" Rodriguez Quote Share this post Link to post Share on other sites
