Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
Styrofoam is an excellent insulator.
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
200,000 joules of heat are needed to produce a single styrofoam cup. In order to simulate the waste of a styrofoam cup, its ceramic counterpart would have to be used 70 times or washed over a thousand times to offset the loss of heat in one styrofoam cup.
400 YEARS.... !
Heat will do it
No, or else it would not be made as a cup.
Gasoline will melt right trough a styrofoam cup.

a cup made out of styrofoam...........................................................................................................................................................................
if its a small Styrofoam cup definitely not
Styrofoam cup is a good insulator because it is coated with foam
Hot chocolate will stay warmer in a Styrofoam cup.
the answer is styrofoam idiots
A Styrofoam cup weighs about 4.4 grams.
Normal windshield washer fluid contains methanol. Rubbing alcohol is isopropyl alcohol. Assuming that your rubbing alcohol is 70% alcohol, I would mix 1 cup of alcohol for every 2 cups of distilled water. If you use tap water, you could get mineral deposits in your windshield washer tubing. Also, I wouldn't try using rubbing alcohol in an older car, because it might still use rubber tubing. This would be damaged by the isopropyl alcohol.
