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. Dry ice is frozen carbon dioxide. It will keep perishable foods colder and longer than traditional ice. It is an excellent refrigerant for shipping, camping and bulk use. Unlike traditional ice that melts into water, dry ice turns into a gas appearing like fog or steam.. Ice should be clear in color as well as odorless and tasteless. When purchasing ice, look for bags that are properly closed and secure (no drawstring ties). The bag should carry the manufacturerâs name and address. Also look for the International Packaged Ice Associaton (IPIA) symbol.
