It's the flooding problem most of all. I'm in one of the few Manhattan co-ops that still allows washing machines and dryers and it's a wonderful thing to have it in my apartment. But many landlords, co-op board and condos don't permit them because of the flooding.
Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice.
A teaching laboratory demonstration for the production of dry ice is to use a carbon dioxide fire extinguisher with a porous fabric collecting bag over the nozzle. The expansion of the gas lowers the temperature enough to produce dry ice snow that is collected in the bag.
