Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
plastic cup will make it be the coldest

Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
styrofoam, but warning fammable and unsafe for the environment!
because they are good conductor of heat which allows theheat to pass through the bottle and make the water warm
No. Use Styrofoam.

Styrofoam cups will keep a hot drink warmer for a long time. Insulated cups will also keep your drink warmer longer.
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet. Especially if it's a foam of some sort; the air bubbles in the foam create barriers that heat energy has to cross to be able to escape.
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
Yes, because it does not conduct heat.
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
It's a better insulator
