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.
If your talking about boob sizes a d cup is greater xD
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.
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.
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.
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!
The Mass Of A Paper Cup Is About 1.95grams
Plastic is bad for the environment and foam isnt
The thin plastic cup is a poor insulator.
