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.
A couple of my friends and I made hot ice for our school science fair. We used sodium acetate. This project won first place at my schools science fair!!! Materials: Stove. Pot. A spoon. A glass cup. and Sodium acetate (you can find it online or in certain heat packs). How to do it: You heat water in a pot and put the sodium acetate in the water.
Hazards of Dry Ice. Dry ice is the solid form of carbon dioxide. It is non-combustible and is available in flakes, pellets, or block form. Dry ice will sublime (vaporizes directly to the gas state) at a temperature of -78.5 C (-109.3 F) or higher. Dry ice is commonly used to cool reactions or to ship biological specimens. Dry ice is considered hazardous three reasons: 1  Explosion hazard: dry ice releases a large volume of carbon dioxide gas as it sublimates. 2  Suffocation hazard: a large volume of carbon dioxide gas emitted in a confined space, or other unventilated area (e.g. cold room) may create an oxygen deficient atmosphere.
