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.
1 When using dry ice for cooling foods, place the dry ice in the BOTTOM of a cooler, refrigerator, or insulated container. 2  Do not allow foods to have direct contact with the dry ice. 3  Place an insulating material â such as cardboard â between the dry ice and food. 4  Do not put dry ice in your drink. When using dry ice to keep foods frozen, place the dry ice ON TOP of the items you want frozen. 2  A small block of dry ice (5 to 7 pounds) wrapped in an insulating container has an effective cooling time of 18 to 24 hours.
