Things which keep warm things warm and cold things cold are referred to as insulators.
Aluminum foil is better at keeping things cold because it reflects heat and light, which helps to maintain lower temperatures. Plastic wrap does not have the same insulating properties and is more prone to tearing or losing its shape when exposed to cold temperatures.
Cloth is not a good insulator for keeping cold things cold because it does not have strong insulating properties. It can easily allow cold temperatures to pass through. Materials like foam, plastic, or vacuum-sealed containers are better options for insulating cold items.

A plastic cup may help insulate cold water for a short period of time, but it is not as effective as an insulated container. The thickness of the plastic and the ambient temperature will also affect how long the water stays cold.
A plastic cup can be use for a number of things. It can be used for drinking beverages or for storing things. Paper clips and pens are some of the things you can keep in a plastic cup.
