This is a trick question, the size of the rock and the plastic cup varies. Normally, however the rock is commonly the one with more mass.
Since oil will float on top of water, we can assume that the weight (or mass) of water is greater than that of oil.
A plastic cup is a good conductor of heat, meaning it allows heat to transfer quickly out of the cup and into the water, helping it cool down faster. The plastic material also has less thermal mass than glass or ceramic, so it cools down faster itself, helping to cool the water more efficiently.
If your talking about boob sizes a d cup is greater xD
Plastic is less dense than glass, so normally a plastic cup is considerably lighter than a glass cup, although in theory a very small glass cup could weigh less than a very large plastic cup.
Heat evaporates moisture in the plant matter beneath the plastic sheet which recondenses on the plastic and runs down to the rock in the center, dripping into the cup or container.
Who was Tracy who drinks for a plastic cup
Where in the world did that idea come from ? Compare an iceberg the size of California and a cup of coffee.

A plastic cup can be recyclabe but it's definitely not renewable.
The weight of a plastic cup can vary based on the size and thickness of the cup. On average, a small disposable plastic cup weighs approximately 5-10 grams, while a larger plastic cup can weigh around 15-30 grams.
The process is called desalination. The most common way is by simple evaporation. You need plastic wrap, a rock, a bowl, a cup, and of course... salt water. Fill the bowl 1/3 ways with salt water and place the cup in the direct center of the bowl. Cover the bowl with plastic wrap and then place the rock in the center of the plastic wrap so that it is directly over the cup. The wrap should be slightly caving in above the cup. In survival you can use the sun, but if you have the resources use a high-powered light. Shine the light directly over the bowl. Leave the bowl untouched for a few hours. The water in the bowl will separate with the salt and condense on the plastic wrap. The rock will drag the droplets over the cup and gravity will drop it into the cup. And there you have it, fresh H2O!
