Using Saw Dust, Aluminum Foil, and Copper, It is impossible to keep an ice cube from melting, without one condition. The external ambient temperature would have to be below freezing.
You could slow down the rate the cube melts, but not halt it without a continuous supply of cold air to keep the container below freezing.
Saw dust is a decent natural insulator. Heap it on thick enough and it will act as thermos or a cooler.
Note that just like a cooler or a thermos this doesn't really stop the melting, it only slows it down. As long as the surrounding temperature is above freezing the ice cube is going to melt eventually. The only real way to keep it from melting for a long time is to put it somewhere where the temperature is below freezing, like in a freezer.
It is used to stop heat taken in by radiation as al is a good reflector of heat
One way to keep an ice cube from melting away is if you keep it in ice water.
saw dust aluminum foil and copper
it melts
Yes it does.
Ice cube with salt. The salt disrupts the lattice formation in the ice, lowering the melting temperature. As the salt melts ice, the surface area exposed to the salt increases, further perpetuationg the reaction.
you can put sawdust on the ice cube
Obviously putting it in the freezer will keep it from melting. Other good insulators are: - Styrofoam - Bubble wrap - Copper

how do i keep and ice cube from melting with out foam for 8 hours
Well, first thought would be keep in in the freezer. Covering the ice cube with an insulating material would help, sawdust or woodchips is what they used to use many year ago.
You use insulating materials like foil or copper or sawdust. Bubble wrap and styrofoam work good, too.
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
