A few "college tricks" I know of......
I've never used them for ice cream, but the concepts are the same.
Saline solultion will definitely get colder than regular water/ice alone.
Don't plan to freeze the solution, just mix it when you need it.
Pouring a thin layer of ethyl-alcohol atop a metalic plate of sufficient
thickness directly abutting the surface of what you wish to cool, then
proceeding to set it alight can act to substantially reduce the temperature
of the side of the place in contact with your surface (while heating the
other side).
When all else fails and you're icecream is melting....
Pull out your fire extinguisher and make a big, expensive cloud. The CO2
being released from the extinguisher is SUPER cold as it comes out (even
makes the cylinder cold, but that's from the sudden phase change). You can
absolutely freeze things, even to sub zero, with a fire extinguisher. I once
saved a warming beverage this way, the extinguisher I had in the vanagon was
JUST the right size to do 12 oz of liquid from 50* to 40*.
Also cold storage for long term is all around you, you just have to know
where to dig and how deep.
