Forever if you leave them in the freezer! But it melts in hours.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Obviously putting it in the freezer will keep it from melting. Other good insulators are: - Styrofoam - Bubble wrap - Copper
Use clay,rubber, wax, seaweed and styrofoam
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.

One way to keep an ice cube from melting away is if you keep it in ice water.
how do i keep and ice cube from melting with out foam for 8 hours
you can put sawdust on the ice cube
store the ice in a cool storing place
keep it in the cooler
probably if you keep it in the freezer
You could keep it in a freezer.
You could keep it in a freezer.
simple the melting point of water is approximately 30 degrees Fahrenheit so keep the atmosphere around the ice cube less then 30 degrees Fahrenheit and your ice cube will not melt
Pour salt on it; it will postpone melting.
Put salt on it.
