Ball bearing wort chillers
 
Just a thought but if one could find ss ball bearings would they make good wort chillers by freezing after boiling and tossing in the kettle? I've seen a number of people advocate sanitized ice for top off water but this would be easier to store and sanitize I think.

A floating ice wand would probably work better. Than you can start a whirlpool with the wand and be chilling it at the same time, then just let it float as the beer continues to chill. Granted you might need a couple of them.

I don't see it working to chill effectively for more than 20 seconds tops. But it could be an intersting experiment so if you try it please let us know what you find!

This is a bad idea. The reason ice works so well for cooling is that before it starts to melt it absorbs a ton of heat to provide the energy to break the hydrogen bonds that keep it frozen, so it absorbs much more heat than just what it takes to heat up from freezing temperatures. Without the phase change, any other 'freezing-temperature' material absorbs much less heat even if it starts out at the same temperature.

I'm not usually the one who says this kind of thing, but how cool would it be to say I cool my wort by sticking my balls into it.

Don't think it would work, have no idea about the scientific info above however.

If you pre-chill the ball bearings in liquid nitrogen first it might work.

I love practical solutions!

Ok, Einstein. What if you FROZE the liquid Nitrogen first, THEN added to the wort?? Say goodbye to your Hydrogen bonds! :rockin:

Sounds explode-y.

Also, there wouldn't be any convection going on. The balls would just adjust to the temperature, then sit there.

I think you'd have to jiggle your balls for it to work.

Water has over 8 times more heat capacity than stainless steel (by mass). You'd be far better off using water ice, either directly or contained in a bottle that you can sanitize.
