Question

For science class, I have to keep an ice cube from melting by building a device. I cannot use insulation, and if I do I have to make my own insulation. I also cannot use styrofoam. What are some materials or things I could use?

Answer 1

try using hay

Answer 2

An ice cube melts because it absorbs heat from the surrounding environment. You want to prevent this heat from reaching the ice cube, so you'll need something that doesn't conduct heat very well. Examples of things that don't conduct heat well include styrofoam, cotton, wool, wads of paper towels, etc...

Answer 3

Use newspaper

Answer 4

how about surrounding the ice cube with some aluminum foil, then surround that with an absorbent layer of something that is soaked in a volatile liquid, or even just water,
then if you gently blow on the layer soaked in liquid it should stay cool - maybe you've felt that cooling effect on your hand when some liquid evaporates ?
just an idea to consider, something more than simple insulation.
