You could keep it in a freezer.
keep them in a place 32 degrees or lower
Obviously putting it in the freezer will keep it from melting. Other good insulators are: - Styrofoam - Bubble wrap - Copper
Stuff it into a styrofoam cup with cotton and aluminum wrapped around it and put heaps of salt on the ice cube
There is no way to melt ice without heat. If you see ice melting, you know that it is absorbing heat. There is no other way for this to happen.
The best way to preserve ice is to keep it in an insulated space. Coolers and freezers are the best places to store ice to preserve it.
Put it in somewhere cold, or block the Sun's rays from hitting it with a tarp or something, or insulate it with cloth to keep the cold in and the hot out.
You use insulating materials like foil or copper or sawdust. Bubble wrap and styrofoam work good, too.
