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.
If the ice has salt on it, it will melt at a lower temperature, and will be colder than ice melting without salt on it. Heat will then travel faster from the warm air to the colder ice than to the warmer ice.The salt will only affect that part of the ice with which it comes into contact.f the ice has salt on it, it will melt at a lower temperature, and will be colder than ice melting without salt on it.
