what are some ways to melt an ice cube without electricty use ?

You can hold it in your hands\nYou can breath hot air on it\nYou can put it in the sun\nYou can put it in water

Get a couple of fans and make a "wind tunnel" effect, to move air thru your room, and not just push it around.  By pulling air from another room, you should be able to cool down yours.\n\nI found that putting a bowl (metal works best) of ice in front of a fan will cool things down until the ice melts.

If you want to make a "cloud effect", you can use dry ice.\n\nWhat are they, how to get them, and how to handle them, see the link

If you rub the ice with the fleece then friction introduces heat to the ice and may melt some.  \n\nIf you wrap ice in fleece on a warm day then the insulating properties of fleece will reduce the rate at which it melts.

I would use a length of nichrome wire (see links below) stretched between a couple copper blocks. You could make some sort of pinch block out of the copper and connect a power supply to the copper. (or drill a hole through it with a set screw, tap a hole and us a pan head screw)  You will have to insulate the copper from the rest of the world so you don't short something out.  G-10 (a glass/epoxy resin) makes a good moderately high temperature insulator.  One of the contacts should be fixed and the other allowed to "float" and allow for changes in the length of the wire due to heating.  A spring could be used to provide tension or an air cylinder.  The power supply will depend on the length and diameter wire you choose.  If there is a problem with the electrical contacts heating up, you could run some cooling water through them.  Just drill a hole through it and 1/8 NPT pipe tape both ends.  You can plumb some water to it and it will keep the copper chilled.

Melting.  What happens to ice cubes when you take them out of the freezer

actually you dont need warm water to dissolve ice, once ice is exposed to a higher temperature than its own it will melt, thermodynanics.

Put water under a vacuum. It will boil at room temperature. \n\nOr do you just want to create the illusion of steam? You could put dry ice in water. Then it will be could and appear to be steaming and boiling. And many people will think it is steaming.

Use cardboard, clay, or sugar cubs.  Cardoard would be the easiest.

Use dry ice. It is always -78 or colder.

Pure water.  The ice will have to melt before it could boil.  Water doesn't go through sublimation

Ice-cubes does the same thing, and cheaper!!!

Could Ice be used to produce fire?\n\nSure, fashion the Ice into a lens and use the lens like a magnifying glass to ignite a fire.  If that's what your asking.

Use ice to chill it, or put it in the freezer, then rub with ice. Pick at it gently. Keep icing as you work.

"A heat pack like the one you are describing contains sodium acetate and water. It turns out that sodium acetate is very good at supercooling. It "freezes" at 130 degrees F (54 degrees C), but it is happy to exist as a liquid at a much lower temperature and is extremely stable. Clicking the disk, however, has the ability to force a few molecules to flip to the solid state, and the rest of the liquid then rushes to solidify as well. The temperature of the solidifying liquid jumps up to 130 degrees F in the process.\n\nWhen you boil the solid, you melt it back to the liquid state. You have to completely melt every crystal, by the way, or the liquid will quickly re-solidify. You can repeat this cycle forever, theoretically, just as you can freeze and melt water as many times as you like. The plastic pouch eventually wears out and leaks, though (since sodium acetate is a food additive, it is non-toxic)."

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

You of course need to add heat in five separate steps:\n\n1.  Heat the ice from -20C to 0C\n2.  Melt the ice at 0C\n3.  Heat the water from 0C to 100C\n4.  Boil the water at 100C\n5.  Heat the steam to 120C\n\nThe last step (5.) will depend on whether the steam is saturated at an elevated pressure or superheated at one atmosphere which you don't specify.\n\nThe rest is pure calculation using the values for specific heat for ice, water and steam plus the latent heat of freezing (reversed) and the latent heat for evaporation.  Engineers would use a steam table or charts to evalute the steam portion of the problem.
