wether there's a liquid that can be frozen without experiencing expansion? ....also the availibility of that said product?
I'm working on a theory and i need to attain such an item.
it's got to be contained into aluminum too, so it'd be great if the substance was a non-reactant/ corrosion inhibiter with said metal....or even plastic.
water's obviously not an option, cuz we all know what happens when you leave a pop can in the fridge overnight
your help's greatly appreciated.
